Table QW-451.1 has been revised to incorporate the provisions previously found in QW-403.7. That paragraph dealt with how to qualify for welding of materials that were over 8 inches (200 mm) in thickness, and it has been deleted. There is a new line in QW-451.1 that says that, for test pieces that are 6 inches (150 mm) thick, the minimum thickness qualified is 3/16 inches and the maximum thickness qualified is 1.33 times the test coupon base metal and weld deposit thickness.
