ALL NATIONSAltitude Producing the Profit CustomerManagement Toward All Over the WorldFlaw Detection-Radiography vs. Ultrasonics
Both techniques have practical applications and are complimentary in many cases
Each is known to have strengths and weaknesses when detecting flaws
Almost polar opposites in what type of flaws they detect best

Flaw Detection-Radiography vs. Ultrasonics
• UltrasoundMost sensitive to 2
dimensional discontinuities such as cracks, lack of fusion, etc
• RadiographyMost sensitive to 3
dimensional discontinuities such as slag, porosity, and lack of penetration

ALL NATIONSAltitude Producing the Profit CustomerManagement Toward All Over the WorldFlaw Detection-Radiography vs. Ultrasonics
Radiography– Classification of defect is
almost always required (i.e.
crack, porosity etc).
– Typically no way to size in depth/height plane.
– Acceptance criteria often varies by type of flaw detected and are often based on stringent good workmanship criteria
Ultrasonics– Classification of flaw may not
be required.
– Sizing of flaw in length and
height planes usually emphasized
– Allows fracture mechanics /ECA acceptance

Comparison of Data Interpretation
• Ultrasonics (digital file/reports) to Radiography (film, digital, reports)
• Ultrasonics typically color based to emphasize inspection purpose– Amplitude response
– Thickness/depth/TOF
– Indications typically less subjective than radiography

ALL NATIONSAltitude Producing the Profit CustomerManagement Toward All Over the WorldWhat is AUT
• Automated Ultrasonics
• Can be one technique or combined
• Can be semi-automatic or fully automatic
• Can be unidirectional/ rastered/ multiple scans
• Can be computer based or run directly off flaw detector unit

ALL NATIONSAltitude Producing the Profit CustomerManagement Toward All Over the WorldWhat is AUT (continued)
Phased Array and TOFD combinations are heavily favored today versus multi-probe systems because of flaw detection and sizing capability as well as reduced hardware and mechanics
Systems more user friendly and less cumbersome then ever, reducing overall investment and training
Code accepted Quality training available
Most common Techniques Phased Array TOFD Conventional Shear/Longitudinal Wave Creeping waves Etc

ALL NATIONSAltitude Producing the Profit CustomerManagement Toward All Over the WorldWhat is Phased Array
Utilizes multi-element arrays
Incorporates time delays for increased control of beams (steering, focusing etc)
Fixed Angle linear and multi-angle sectorial scans most often utilized

ALL NATIONSAltitude Producing the Profit CustomerManagement Toward All Over the WorldWhy Phased Array Technology
Faster Inspection– Performing the same or improved inspection as
other NDE techniques with greater speed, repeatability, and procedure compliance.
Better Inspection– Overcomes Access limitations – Better detection and sizing of flaws through the
use of focused multi angle inspections– Easier characterization of flaws and geometry– Reducing dependence on the skill of the
operator– Ability to record digital data and retain inspection
records– Typically allows one line scans and reduced
footprint/mechanics

ALL NATIONSAltitude Producing the Profit CustomerManagement Toward All Over the WorldPhased Array Advantages
Offers all the benefits of Ultrasonics with the following advantages
– Increased coverage and detection capabilities through multi-angle, electronic rastering and beam control
– Imaging and recordable data in manageable file sizes viewable by all parties as needed.
– Reduced mechanics and difficulties over multi-probe techniques
– Application of traditional ultrasonic acceptance criteria

Code activities – other summaryCode activities – other summary ASTM RP for PA set-up published
ASTM RP for PA of welds published
API generally accepts PA
AWS D1.1 still requires Engineer’s approval
Europeans “behind” on PA and AUT codes
Overall objective: single pass, code-compliant inspections using E- or S-scans, encoded linear scanning for all codes.

High Variance – “Stick” and “Manual” Welds
Not impossible but more difficult
Typically require high level analysis of geometry reflectors by experienced Technician
Difficult to Automate

Thin Wall and Small diameter Inspections
Creates geometry problems for analysis
Resolution and sizing an issue, often go-no-go with Conventional Ultrasound
Weld caps disproportionate to wall thickness may require inspection in multiple legs
Mechanics also an issue with larger footprint of phased array probes
Often clearance is also an issue between process piping etc
Proposed Solution Small dedicated scanner (.084-4.5”)
with .5” clearance Dedicated internally curved probes
for better focusing and resolution of Small defects
