6.7.1 Complete Joint Penetration Groove Weld Qualification. Qualification of welding procedures in any position qualifies for welding in all positions. Welding procedures qualified on pipe shall also qualify for plate and vice versa, and all pipe diameters. CJP groove weld qualifications shall also qualify all PJP groove, plug and slot, and fillet welds when the tests and requirements of 6.7.1.1 are met.
6.7.1.1 CJP Groove Weld Requirements. Table 6.3(A) shows the type and number of test specimens required for qualification and the ranges of base metal and deposited weld metal thickness qualified based on the qualification test.Test criteria shall be as specified in 6.9.3.
6.7.2 Partial Joint Penetration Groove Weld Qualification. Qualification of welding procedures in any position qualifies for welding in all positions. Welding procedures qualified on pipe shall also qualify for plate and vice versa, and all pipe diameters. PJP groove weld qualification shall also qualify all plug and slot and fillet welds when the tests and requirements of 6.7.2.1 are met.
6.7.2.1 PJP Groove Weld Requirements. Table 6.3(A) shows the type and number of test specimens required for qualification and the ranges of base metal and deposited weld metal thicknesses qualified based on the qualification test. The qualification test weldment shall be similar in groove design to that used in construction, except the depth of the groove need not exceed 1 in [25 mm]. For tension and bend test specimens, after welding, the excess material is machined off on the root side of the joint to the thickness of the weld size and testing is performed in accordance with 6.9.2.1.
6.7.2.2 As required by Table 6.3(A), PJP groove welds shall have three macroetch cross section specimens taken to demonstrate that the designated weld size (obtained from the requirements of the WPS, or design specification as applicable) are met [see 6.9.3.4(1)]. For the macroetch test, any stainless steel listed in 1.4.2 may be used to qualify the weld size.
另外，这是不锈钢焊接工艺，D1.1规范有规定吗？谢谢
