Here is why I am having so much trouble with the code. I have performed a CJP groove weld qualification test coupon and have had the tests performed per paragraph 4.3.1 which references Table 4.2. In Table 4.2 (A) Groove Welds, note 1 states “Partial joint penetration groove welds only” for macroetch testing. Therefore there is not a requirement for CJP groove welds to be macroetched.
In paragraph 4.1.7 it states “Qualification of a CJP groove weld qualifies for all PJP groove welds, plug and slot, and fillet welds.” Therefore the PQR without macroetch testing can be used to develop a single WPS for the joint designs of CJP, PJP, Fillets and etc.
I do not understand why the code would specify macroetch testing to determine the extent of fusion if it has already been proven through the bends and tensile testing required in Table 4.2 for CJP. If it has been proven that the variables can achieve a complete joint penetration, why is partial joint penetration in question?
