S3[www.des ignnews.com] 09.13.04 FASTENING/JOINING/ASSEMBLY SUPPLEMENT

Time was when OEM designerssteered clear of complex plastic shapesmainly because they were too difficultto assemble. Now, however, that maybe changing. Thanks to growing popu-larity of infrared welding, manufactur-ers may now be able to specify intri-cate curved shapes that would haveonce been off limits for plastic parts.Automakers are said to be looking atthe process for curved headlight andtaillight assemblies, as well as the newbreed of radio-controlled key fobs.Makers of industrial piping and tubingare also considering the technology asa means of eliminating mechanicalassembly methods, such as snap-fitsand tongue-and-groove joints, forproducts in chemical plants thatrequire seamless connections.

“Complex shapes that at one timecould only be done by sealants andmechanical techniques can now bedone by infrared welding,” saysGeorge Ritter, principal engineer foradhesives, composites, and plastics atthe Edison Welding Institute(Columbus, OH). “It’s allowingdesigners more freedom to make thekinds of parts they want to make.”

Infrared welding, which can onlybe applied to plastic materials thatflow under applied heatand pressure, appeals tomanufacturers becauseit is relatively simpleand requires a minimalcapital investment. Inits simplest form, thetechnology employs alight source to produceradiation wavelengthsvery close to visiblered, typically about 1µm. Researchers haveeven succeeded with itby employing parabolicreflector bulbs, likethose used in projec-tors. They’ve alsoapplied so-called“neodymium YAG”(neodymium yttrium alumina garnet)lasers, typically operating at 1.06 µm,to generate sufficient heat and pressureat a joint and thus create a weld. IRsystems also need a susceptor materialat the interface of the two parts to bewelded in order to absorb the lightenergy and generate the necessary

heat. But the process typically doesnot require extensive clamping or fix-

turing of parts and therefore is easilyapplicable to complex shapes, includ-ing compound curves.

“When you have complex curves,it can become extremely difficult tofixture plastic parts for ultrasonic weld-ing or vibration welding,” Ritter notes.“That’s where infrared becomes a good

candidate. The fixturing is simple; it’scheap; it’s fast; and it’s broad-based interms of material applicability.” Indeed,materials experts say it can be applied topolyethylenes, polypropylenes, fluoropoly-mers, vinyl, and other thermoplastics.

That’s why thetechnology couldappeal to automak-ers, who in recentyears have begun toconsider more com-plex, curved head-lights and taillightsto enhance the aero-dynamic qualities ofnext-generation vehi-cles. The technologyis also well suited tohandheld automo-tive key fobs, whichtypically employcurved shapes.

Similarly, thetechnology is beingconsidered for use inplastic piping and tubing systems in chemi-cal plants because it provides a seamlessjoint without the use of couplings or adhe-sives that could contaminate the fluidsflowing through the pipes.

To be sure, infrared welding has its lim-itations. With infrared, as with some otherforms of plastic welding, reinforced materi-als can be a problem. Often, fibers or fillershave a tendency to line up in parallel withthe weld interface. “It’s a little bit like logs

floating down ariver,” Ritter says.“They line up paral-lel with the riverbank.” As a result,weld joints of fiber-filled materials runthe risk of beingheavy on plastic andlight on reinforce-ment, and thereforeweaker than sur-rounding materials.

Still, Ritter pre-dicts there will beno shortage of can-didates for infraredwelding solutions.“To get uniformwelding along an

interface is difficult with complex shapes,unless you have a technique like infraredwelding,” Ritter says. “That’s why it’sstarting to make in-roads. It does the joband does it inexpensively.”

ADVERTORIALSENTRAL ASSEMBLIES BENEFITS FROM HELLERMANNTYTON As Operations Manager for Sentral Assemblies andComponents Inc., Bill Schlitz had three main objec-tives when selecting an automatic cable tie tool system: to increase capacity, mobility, and efficien-cy. Sentral Assemblies and Components is a custommanufacturer of wire harnesses, wire leads and lead sets, cable assemblies, as well as electro-mechanical assemblies.

Through significant investments in the latestinnovations in assembly equipment, Sentral hasautomated much of their production. All ofSentral’s cable and harness assemblies are customand, as a result, a tool system that can easily bemoved from station to station to accommodatechanging production requirements is imperative.Schlitz explains, “Without the dependence of anair hose and base unit, the AT2000 has allowedus a great deal more portability. It was also moreeconomical as we are doing 2.5 times the volumewith increased efficiencies.”

With changing production environments, flexiblemanufacturing initiatives have been important areasof concern for many companies. As an industryleader in the development and manufacturer ofcable tie installation tools, HellermannTyton offersthis flexibility while providing a distinct, competitiveadvantage to its customers through automationand improved processes. Sentral was able to maximize their capital and labor investments whileadapting the tools to the manufacturing require-ments for each job.

The switch to HellermannTyton’s automatic cabletie tools has also offered additional benefits to theassembly personnel at Sentral through heightenedergonomic benefits and easy operation of the tool.The tool’s self-diagnostic LCD information paneleasily guides the user through the cycles of cabletie installations. Schlitz says, “The learning curve isvery short with the tool, and if an issue comes up,the operators are able to quickly clear the tool andget back to work.”

HellermannTyton offers support to meet the individual needs of the customer. Expert techni-cians are available for on-site training, and an in-house team of service and support specialistsprovide telephone and online technical support.Schlitz comments on his experience withHellermannTyton’s tool systems support, “Whenoccasional maintenance is needed on the wearparts, our experience with HellermannTyton’sservice and support has been great.”

In addition to automatic cable tie tool systems,HellermannTyton also offers a complete line of pneu-matic tool systems and mechanical cable tie tools.

Infrared welding is capable of eliminatingthe need for snap fits and other mechanicalassembly methods.

Joining plastics too often requires a second-ary operation, a manufacturing step thattakes place after the individual parts havebeen made. But a new technology fromDuPont Engineering Polymers(Wilmington, DE) joins plastic parts in afar more productive place—inside the mold.

Called DuPont Structural Bonding,this patent-pending method involves the

insertion of a micro-porous tielayer to thejoint interface between plastic components.

During joining operations, the plasticsmelt at their interface and interminglewith the tielayer, creating a strong “micro-mechanical anchors.” Nandakumar Rao,DuPont’s global technology director, char-acterizes this physical bond as structural,capable of obtaining burst-pressure

strengths in the neighborhood of 100 psi.And one of the best things about themethod is that it addresses dissimilarmaterials. According to Rao, the physicalbond created within the tielayer—which ismade from a proprietary non-wovenfabric—overcomes the chemical incompati-bilities thatoften occurbetween dif-ferent familiesof thermo-plastics.DuPont hasalready triedthe method with a wide variety of materialcombinations, including difficult-to-bondcombinations such as polyethylene.

DuPont scientists developed themethod primarily as a way to join over-molded parts inside the tool. In thisimplementation,the tielayer wouldbe inserted in themold betweenthe first and sec-ond shots. Raosays this variantof the bondingtechnology wouldcome in handy asa way to supple-ment the usualmethods used tojoin soft-touchelastomers torigid plastic sub-strates. Currently,design engineersmust mold in mechanical interlocksbetween the soft and hard plastics. Orthey can sometimes rely on chemicalbonds between the soft and hard compo-nents, limiting their choice of elastomersand substrates. “Not only are the choicesof elastomer limited, but poor bondstrength can lead to delamination between

the two components,” Rao says. The new bonding method also has

implications beyond overmolding. Raosays it can join plastics as part using tradi-tional welding methods, as long as theybring the two surfaces of the plastictogether in their molten state. “If you can

melt it, you canjoin it,” Raosays. DuPonthas successfullyused theStructuralBonding tech-nology with

vibration welding equipment, for example.The company is looking at the bondingmethod’s compatibility with ultrasonicand laser welding. “With laser welding wewould need one of the parts to be trans-parent to the laser to allow its energy to

reach the jointinterface,” Raocomments.

The newstructural bondingmethod targets avariety of applica-tions beyondovermoldingsoft-touch elas-tomers. Rao saysone of the mostpromising appli-cations involvescombining low-cost and high-per-formance plasticsas a way to create

cost-effective, emission-resistant fuel han-dling components. For example, DuPonthas welded polyacetal components to thesurface of polyethylene fuel tanks.

When assembling printed circuit boards,electronics manufacturers face a difficultchoice. They can deal with the incon-venience and poor productivity of loosefastening hardware. Or they can usebroaching fasteners, which hold circuitboards securely but can too easily dam-age fully populated boards if no installedproperly. “Electronics manufacturersdon’t really like either idea,” says JayMcKenna, special products manager forPennEngineering Fastening Technologies.“But they haven’t had much of achoice.” Until now.

PennEngineering recently came upwith a system that uses surface mounttechnology to add fasteners to printedcircuit boards. Called ReelFast SMT,the system adheres various types of fas-teners directly onto a solder pad on thesurface of the PCB, using the same sol-dering processes as the board’s elec-tronic components. “The fastenerbecomes just another board compo-nent,” explains Brian Bentrim, a seniornew product development engineer forPennEngineering.

REALLY FASTBecause the new fasteners have to workwith surface-mount assembly machines,they’ve been designed with productivityin mind. As the name suggests, theReelFast parts typically come in tape-and-

reel packages suitable for usewith existing pick-and-placerobots. McKenna says theReelFast components installin about 0.3 sec, versus asmuch as 30 sec for a broach-ing fastener. “Not only is thenew system inherently fasterbut it also eliminates a sec-ondary operation,” he says.

The new system alsoseems a bit less risky.Manufacturers typicallyinstall broaching fastenersonce the boards have beenfully populated with electronic compo-nents. But the broaching process, whichsubjects the boards to significant amountof stress, can ruin PCBs when they’re attheir most expensive. For example, installforces for a typical broaching fastenercan hit 700 lbs. ReelFast install forces, bycontrast, reach a maximum 2.25 lbs. Andthough the ReelFast system currentlyrequires a pilot hole through the board,“that hole is drilled in an inexpensiveunpopulated board rather than broachedin an expensive populated board,”Bentrim says. What’s more, Bentrimbelieves that the pilot hole may proveunnecessary as the brand new ReelFastsystem develops further.

Once installed on the board, theReelFast hardware exhibits nearly as

much strength as an equivalent broach-ing fastener. According to McKenna, aReelFast retaining nut installed in a0.25-inch hole has an average push-outstrength of at least 85 lbs and an aver-age torque-out strength of 33 inch-lb.In the same tests, PennEngineering’scomparable broaching style achieved apush-out strength of 95 lbs and torque-out of 35 inch-lb. In both cases, “thecircuit board will delaminate before thefastener fails,” McKenna says.

SEVERAL STYLES Over the next months, PennEngineeringplans to offer the new surface mount fas-teners in several styles. The first one is aReelFast version of the company’spatented panel fasteners. In this case,


PCB Assembly Gets ReelA new surface mount technology takes aim at circuit board installation difficulties

By Joseph Ogando

Rather than broaching the board, the ReelFast systemattaches fasteners to the board as a surface mount com-ponent. This surface mount method currently requires a small pilot hole, but it’s drilled in an inexpensive, unpop-ulated board rather than broached in an expensive, fullypopulated one.


the fasteners metal retainer adheres tothe board while a proprietary plasticcap-and-screw snaps in place by hand.With these caps snapped on, the screws,which can be hand- or tool-tightened,become captive to the board even whenre-used. So this style benefits applica-tions that require easy removal and re-

installation of circuit boards.They also have a cosmetic benefitin that the colors of the thermo-plastic screw cap can be cus-tomized to match chassis colors.Thread sizes for ReelFast panelfasteners include M3, M3.5, #4-40, and #6-32.

Next up, PennEngineeringwill also put out ReelFast stand-offs. “Stand-offs and screws arestill the most popular way toattach circuit boards to the chas-sis,” McKenna says. And for appli-

cations where easy removal of the boarddoesn’t matter, the stand-offs will be alower-cost alternative to panel fasteners.

Finally, the company will soonintroduce a surface mount version of its“R’ Angle” right-angle fasteners. Thisstyle of fastener wasn’t previously feasi-ble for PCB applications because the

manufacturing processes used to makethe R-angle couldn’t produce theknurled feature needed to broach theboard. With surface-mount technology,the need for the knurled feature disap-pears, and the R-angle opens up severalnew design possibilities. In its mostobvious implementation, it enables per-pendicular connections between circuitboards and chassis. But less convention-al applications are also emerging. Forexample, the R-angle is under evalua-tion as a way to attach a threaded anten-na to the board, saving loads of spacecompared to traditional mounting tech-niques. “One of the neat things aboutsurface mount technology is that ithelps engineers think outside the box,“Bentrim says.

Hot Melt ApplicatorFor high-volume bonding

The Polygun AE II Applicator from 3M combines the best features of a high-volume industrial system into a compact,

self-contained applicator. Thisrugged, 20-oz power tool is engineered for the professional,but the price compares favorablywith those of a consumer gluegun. Warm-up is only 3 min andadhesive flows at 4 lbs/hr to keepup with assembly line speeds. In addtion, the 250W positive temperature coefficient (PTC) system maintains 400F (204C) for

application and bonding consistency all day. The built-in standhelps keep the applicator upright, stable, and ready to grip,and the positive check valve nozzle helps minimize messy drips.Users can take full advantage of this high-volume applicator bymatching it up with the new Jet-Melt General PurposeAdhesive 3750 AE from 3M.

Helical Grooved PinsFor high-shear applications

Spirol International Corp. has introduced a line of standard inch and metric helical grooved solidpins for applications where a grooved pin is installed into a hardened hole. With standard groovedpins, the high peaks tend to shear off during installation, causing retention problems and field failures. These new helical grooved pins solve this assembly challenge by utilizing a unique grooveconfiguration. Wide, low-profiled peaks spiral about the body of the pin, allowing the pin to

maintain its integrity when installed into a hardened hole. These helical grooves provide low and consistent installationforces, compared to common solid pins.Spirol offers these grooved pins in threestyles for specific applications: SeriesGP200 Full Length Groove; Series GP210Half Length Centered Groove; and SeriesGP220 Half Length Offset Groove.


ADVERTORIALAUTOSPLICE SLICES PART COSTS WITHHELP FROM MISUMI CATALOGBy outsourcing the production of its mechanical com-ponents to Misumi of the Americas Inc., AutospliceInc., a worldwide manufacturer of innovative inter-connection machines and connectors for the electri-cal and electronic industries, realized per-part costsavings of up to 70 percent.

Headquartered in San Jose, CA, Autosplice cred-its its success to an enterprisewide commitment toinnovative design, balanced with an overriding con-cern to contain costs. Looking to improve cost effi-ciencies, David Shealey, Autosplice’s Director ofInternal Production Machine Development, beganpurchasing components from Misumi several yearsago after receiving a catalog.

Shealey says, “The Misumi catalog is a design engi-neer’s candy store with a huge variety of custom partsavailable quickly and in small quantities. We are now build-ing a good number of our custom manufacturing equip-ment from the frame up using Misumi components.”

Shealey estimated that Autosplice’s per-part costsavings ranges from 25 to 70 percent when comparedto in-house production or outsourcing to a localmachine shop. “The fact that Misumi has no minimumorder quantity and has never charged a setup fee orrequested a drawing for a custom component savesus 20 to 50 percent right up front,” he says.

Shealey adds that nearly 90 percent of hismechanical parts requirements, which include linearshafts, bearings, spur gears, collars, and rollers, arenow sourced from Misumi.

“One of the more amazing things was finding thatraw material pieces were available, cut to the desiredoutside dimensions, finished, packaged, and shippedat a very competitive price when compared to cuttingand squaring the stock in house,” Shealey comments.“The cost and time savings are considerable. It’s greatto have one catalog that provides one-stop shoppingfor everything from actuation, control system compo-nents to complete complex machine designs.”

Ron Dziuda, Marketing Manager for Misumi, saysthe time savings experienced by Autosplice andother Misumi customers results from the ability of thedesign engineer to download part drawings directlyfrom the Misumi website, where they can be para-metrically dimensioned and inserted into their draw-ing. Most drawing formats are supported, includingAutoCAD, Mechanical Desktop, Smart Sketch, SolidEdge, Inventor, Pro/ENGINEER, CATIA, IntelliCAD,and TurboCAD, making this feature efficient and easyto use. As the custom components are defined anddownloaded, the part number is established.

“Our customers are looking for the right partneralong with the right parts,” Dziuda says. “Misumi’smore than 40 years of experience working withdesign engineers involved in assembly automationgives us a rare insight into their needs.”

ADVERTORIALROBOT SPEEDS UP CIRCUIT-BREAKERPANEL ASSEMBLY When a major manufacturer wanted to moveits assembly of circuit-breaker panel coversfrom manual operation to an automatedprocess to increase productivity and cutcosts, it called Dane Systems, an integrator ofautomation systems in Stevensville, MI.

The task was to design a system thatwould position the covers for welding ofhinges and other hardware. Not only did thesystem have to be fast, it had to be highlyflexible to accommodate short runs of a vari-ety of panel styles. The test goal was 30welds in a 33-second cycle, including thetime required to position the panel, movewelding heads to specific welding points,perform the welds, and remove the panel.

The resulting system uses a two-level con-veyor—the lower level delivers the panel tothe work cell for welding. After the welding iscomplete, the conveyor carries the complet-ed panel to an elevator, which raises thepanel to the higher level for transport to theunloading station.

Two welding assemblies, one at each sideof the conveyor, perform the welds. Theassembly moves in the X and Y axes on theCKR Compact Modules while air over oilcylinders open and close the welding gunheads.

“The 33-second cycle time was aggressive,but not unreasonable,” says Mike Galaske,chief operating officer for Dane. “But theneed to accommodate many sizes and stylesmeant that we also needed motion and con-trol systems that were fast, rugged, and capa-ble. We worked with Bosch Rexroth before,so we talked to them about our needs.”

To move the panels, Dane chose theRexroth TSplus, a nonsynchronous conveyorsystem designed for transporting palletedworkpieces. To save space, an over/underconfiguration is used with a vertical transferfrom the lower part to the upper. “The TSplusconveyor is a flexible system for movingparts,” Galaske says.

The 250-lb welding assemblies presenteda challenge. Using a welding head on eachside of the box strikes a reasonable balancebetween productivity and simplicity. The CKRmodules are driven by high-speed servomotors, in turn controlled by a Rexroth rho4.1 controller.

ADVERTORIALSIGNIFICANT PRODUCTION INCREASEWITH 3M JET-WELD THERMOSETADHESIVE SYSTEM “We have more doors than ever going outevery week,” reports Matthew Lomastro,Production Manager, BridgewaterWholesalers Inc. The company serves theEast Coast from Connecticut to Virginia withproducts that include custom hollow coredoors. “We were completing about 75 cus-tom hollow core doors a week,” Lomastrosays. “But now with the 3M Jet-WeldThermoset Adhesive System, we’re up toabout 300 a week.”

The Jet-Weld Thermoset Adhesive Systemis a self-contained system that combines thespeed of a hot melt adhesive and bondstrength associated with a two-part structuraladhesive.

At Bridgewater, the Jet-Weld System from3M replaced white glue for bonding 1- to 1/8-inch square fir reblock strips between hard-board door panels. The Jet-Weld adhesivecartridge is inserted and heated in the 3MJet-Weld II Applicator. A bead of adhesive isthen applied at 250F to the strip and hardensquickly as it cools. Clamping time on thedoor is only 5 min compared to 5 hrs with thewhite glue.

Hot melt adhesive had also been tried butset too quickly, particularly on longer strips.Lomastro notes, “Jet-Weld Adhesive doesn’tset as quickly as a hot melt. A 4-min opentime gives us enough time for even thelongest strips, but the system still shortensour production cycle.”

With Jet-Weld Thermoset Adhesive TE-200, the bond line on each door reaches han-dling strength in about 2 min. Doors arequickly moved out of the way to free up pro-duction space.

Commenting on bond strength, Lomastrosays, “Our doors go into expensive homeswhere customers don’t expect problems.Assembly speed is important to us, but so isreliability.” Ultimate strength of Jet-WeldThermoset Adhesive TE-200 has about 1 tonof holding power.

Jet-Weld Thermoset Adhesive TE-200 isone in a line of moisture-curing Jet-Weld formulations. Choices are available for viscos-ity, open time, handling strength, and a variety of surfaces including wood, plastics,and aluminum. All are 100-percent solids withlow volatile organic compounds (VOCs).

ADVERTORIALDOWEL ELIMINATES FOUR PRECISIONMACHINING STEPSSpirol engineers developed a dowel fora customer’s application that resulted inassemblers replacing four machiningsteps with just one step—saving the cus-tomer time and money.

Spirol International Corp. (Danielson,CT) and a well-known HVAC systemsmanufacturer cut the cost of the con-necting rods used in compressors. Thesolution focused on reducing the num-ber of machining and assembly stepsrequired to fasten a reciprocating pistonto the crankshaft.

Generally, a connecting rod is cast asone piece and then split into halves. Forprecision, the two halves must bemachined at the mating surfaces. Thenormal process is to machine male andfemale halves using steps or staggeredseams for realignment. After this opera-tion has been performed, the two halvesare then reassembled, using bolts to fas-ten them together. One method involvesthe cutting of the connecting rodthrough the crankbore while using twodowel pins to align the halves prior tomachining. The bore is then machined.Precision dimensions on the bore arecritical to the wear life of the connectingrod assembly. The two halves must bereassembled over the crank journal withminimal misalignment.

Spirol uses a rolled-form, high carbonsteel thin-wall dowel bushing to replacethe dowel pin. The bushing is insertedinto the connecting portion of the rod,and the assembly is fastened by passingthe screw through the ID of the bushing,eliminating the need for separate boltholes. Additionally, tolerances for thealignment holes are not as critical due tothe spring action of the dowel bushing.

The new design approach results incost savings: Four machining steps (drillbolt holes, drill dowel holes, chamferdowel holes, and ream dowel holes) arereduced to one (step drill bushing diam-eter and tap-drill diameter). In addition,rework and scrap are reduced, and thedowel bushings are less expensive thanthe pins. Also, the remaining operationscan now be performed on a CNCmachine.

Why does the auto industry need to be con-cerned with joining of dissimilar metals?The auto industry is trying to figure outhow to reduce vehicle weight. But whilethey’re trying to cut weight, out of theirstructures, they need to maintain highdurability. So they need materials like alu-minum to reduce weight and they needsteel for high durability.

The problem is that it’s very difficultto fusion weld aluminum to steel becauseone melts at a higher temperature than theother. Sometimes, when you have materials with different melting points, they can form bad phasescalled inter-metallic phases, which are detrimental.

So if you want to join dissimilar metals, such asaluminum and steel, you’ve got to look beyond fusionwelding. Right now, the best alternatives are solidstate processes and cold processes. The idea is to bringthe dissimilar metals together and suppress the badside effects.

Which dissimilar metals does the auto industry needto be looking at?The most important ones right now are aluminum-to-

steel, steel-to-magnesium, and aluminum-to-magnesium. All of those are materialcombinations that the auto industry wantsto put into vehicles, with the idea of get-ting the best combination of weight reduc-tion and performance.

In Europe’s Smart Car, for example,magnesium cross members have been usedon an aluminum subframe. Automakersalso like to use dissimilar metals on sub-assemblies that they can hang on the vehi-cle frame. Shock mounts, for example, are

sometimes made from magnesium and then attachedto aluminum or steel frame rails.

The biggest use of dissimilar metals, though, is insteel substructures with aluminum skin panels on top.The idea is that steel provides rigidity and crash-wor-thiness and aluminum provides corrosion resistanceand light weight.

Some of the materials you mentioned are used rightnow. How are automakers joining them today?What’s really hot in the industry right now is the useof mechanical fasteners. We use self-piercing rivets,where we plunge a third body through the parts and


Automakers Look to Solid State Welding ofDissimilar MetalsIn the past decade, Jerry E. Gould says increased pressure on automakers to

boost performance and fuel efficiency has led to renewed interest in new welding

techniques, especially for such dissimilar metals as steel, aluminum, magnesium,

and titanium. Design News asked this chief engineer for all resistance and forge

welding activities at the Edison Welding Institute (Columbus, OH), how the auto

industry plans to deal with those materials science challenges.

create a mechanical joint that way. Wealso use what’s called a “clinch,” wherewe push a die in one side of the metaland form the other metal around it.That way, it makes an interference-typefit. We also combine these methodswith adhesives. We actually glue themetals together as a way of making ajoint without having a metallurgicalreaction. All of these techniques are

being investigated very heavily byautomakers today.

So how do you plan to take this to the next level and begin welding these materials?You need processes that allow you tobreak up the surfaces and bring themetals into intimate contact withoutmelting them. Those are more advanta-geous than the processes where youactually melt the material.

The way to do that is through solidstate approaches. Right now, propshafts are starting to go into vehicleshere and in Europe, where steel endpieces are friction welded onto alu-minum shafts. The other technologythat’s gaining a lot of attention is mag-netic pulse welding. Magnetic pulsewelding uses a magnetic field to accel-erate one part, which we call the

“flyer,” into a static target part. Withthis technology, you’re talking aboutimpacting those parts at speeds of1,000 ft/sec.

How does that help solve the prob-lems associated with conventionalfusion welding of dissimilar metals?At those kinds of speeds, you dissipatekinetic energy into thermal energy, so

you get a very finely defined meltzone. Also, the thermal cycles aremeasured in double-digit microsec-onds. And as the thermal cycles getshorter and shorter, you can suppress a lot of the detrimental phases thatyou get with other material joiningsystems.

With the auto industry’s emphasis oncost consciousness, can they actuallyuse any of these processes? Can thesebe considered growth areas?Friction welding, magnetic pulse weld-ing, and some of the other methodsfor joining dissimilar metals tend to berelatively inexpensive. They can beused for high-volume manufacturing,so they’re well suited for the autoindustry. That’s why friction weldingand magnetic pulse welding are reallycoming on right now.

ADVERTORIALDANGEROUS CHEMICALS DISPOSED DAILYWITH STANDARD GRIPPERSSince 1982, SCHUNK has made daily busi-ness of engineering and supplying grippersand automation components that havebecome the standard for reliability anddurability. When the U.S. Army Corps ofEngineers awarded Parsons a $323 millioncontract to dispose of old chemicals, theyturned to SCHUNK for gripping and holdingsolutions. Parsons tasked with criteria devel-opment and facility and process systemsdesigns quickly determined that the processmust be automated for reliability and safety.

SCHUNK’s assignment was to apply grip-pers as robotic end of arm tooling for partsranging from 32 to 100 lbs. SCHUNK appli-cations engineers calculated the require-ments of grip force based not only on partweight but also on process accelerationsand decelerations. It was determined thatoff-the-shelf grippers could easily match theapplication requirements with more thanacceptable margins of safety. These grip-pers are proving themselves every day byreliably disposing of material that no humanshould be handling.

In 1997 the U.S. ratified the ChemicalWeapons Convention treaty that has sincebeen signed by more than 153 nations. Thistreaty prohibits the production and use ofchemical weapons, and further commits theparties to destroy stockpiled material in anenvironmentally safe manner by April 2007.Parsons, together with SCHUNK, is helpingthe U.S. government accomplish this goal.

The SCHUNK gripper chosen for thisapplication was the SPG100 providing 8inches of stroke with 2,250 lb-ft grip force at85 psi of pressure. The work pieces rangedin diameters from approximately 4 to 7inches with more extreme differences inlength from 1.5 to 24 inches. Due to off-center gripping of some parts, the applica-tion calculations became more critical.Based on a 0.3m friction coefficient and anacceleration/deceleration of 2g, therequired grip force was determined to be atminimum 900 lb-ft. Compared to the grip-per force of 2,250 lb-ft, a 2.5 times safetymargin was achieved. The SPG100 wasdelivered from stock, and now have manymonths of trouble-free operation as testa-ment to the choice.
