bend strap measurements for mig tests?

Years ago the test labs cut the straps to be bent from a test coupon 1" or 1-1/4" wide by 6" long. Why are they being cut to 3/8" wide by 3" long now? Would this not create problems with the pass/fail ratio, because these test specimens are subjected to extreme heat?


I believe what you are talking about is a side bend test.

the other dimensions are still used but sometimes, side bends are required by certain codes.

you are correct, the extreme heat could affect the outcome.

AWS and ASME and others still have the same provisions for the wider straps using face bends and root bends.

when the plate or pipe is too thick, side bends are used and also in some instances for qualifying a weld procedure.
