组合焊接工艺的弯曲试验是怎么规定的

马健

asme 9卷 QW-451.1规定了评定弯曲试件，然后note 2说 (2) For combination of welding procedures, see QW-200.4.，但是QW-200.4里面压根没找到关于弯曲试验的内容。然后QW-200.2里面定了个原则：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.

请问大家怎么理解，是note 2搞错了吗，应该是see QW-200.4? 另加入组合是GTAW+SMAW  16mm，怎么选弯曲方式。 GTAW+SMAW+SAW，怎么选弯曲方式？

侧弯能够包含各种焊接方法！

感谢回复，我也知道侧弯可以，我的意思是note2好像有问题
