Plate coupon size for weld performance qualification

by Zhenom
(India)

What is the size(s) of the plate coupon used for weld procedure qualification. Is a single plate 6 inches by 3 inches - making the coupon about 6 in by 6 inch?

Standard plate sizes for AWS welding performance qualification tests are usually 7 inches for 3/8" thick plates but for thicker plates and for procedure qualification they are often longer to provide for more test specimens like tensile specimens or metallograhic testing.
