Subject: [MW:13460] amendment for this WPS regarding
We qualified WPS for Material SA 516(P:1,G:1) TO SA240TP 316L(P:8,G:1) by SMAW process as per ASME Sec IX ,thickness range- base metal Grove is: 5 -30 mm,Filler metal:E309 Mol.
My question is while qualifying we did not mentioned Preheating and Inter pass temperature (in WPS -QW 406),now one of our client asking for these two parameters need to be filled /required, in this case how to convince him. Whether can I make amendment for this WPS, it is acceptable as per ASME Sec IX. If yes can u provide format for this amendment.
