QW-200.2有如下要求:
One or more combinations of welding processes, filler metal, and other variables may be used when welding a test coupon. The approximate thickness of weld metal deposited, excluding weld reinforcement, shall be recorded for each set of essential and, when required, supplementary essential variables. Weld metal deposited using each set of variables shall be included in the tension, bend, toughness, and other mechanical test specimens that are required.
这里明确了各种试验(包括冲击)都要包括每种方法的熔覆金属,但是没有提到热影响区,VIII-1也没有提到热影响区取样要包括每一种方法。我个人觉得不管几种方法组合,焊缝取样包括每种方法且满足UG-84(g)(1),热影响区取样满足UG-84(g)(2)就算是满足了规范的要求。 |
