If a weld should crack during shipment, handling and/or erection, or if the SunShade is damaged, repair of welded louvers is extremely difficult.

Welding reduces outrigger strength. Will the outrigger fail? Do the calculations provided by the vendor allow for reduction?

Configurations including adjacent blade overlap, make access to the weld areas extremely limited.

In the shadow of the blades, welds appear dark. In direct sunlight welds appear as bright spots from all angels.

Mechanical Fastened vs. Welded Assembly

Mechanically assembled extruded aluminum has been an industry standard as well as C/S standard since they were first marketed in the 1940’s.

♦ Configurations including adjacent blade overlap, make access to the weld areas extremely limited. It

is very difficult to perform and inspect the tack welds to insure quality welds with full penetration through the joint.

♦ If a weld should crack during shipment, handling and/or erection, or if the louver is damaged, repair of

welded louvers is extremely difficult. Adjacent welds must be broken to provide access and all broken welds must be cleaned off by chipping or machining. All finishes around the weld must be removed by sanding to prevent contamination of new welds. This causes substantial costs and delays.
