RE: [MW:13464] amendment for this WPS regarding


Dear Kvr,
Yes you can, defiantly you noted Preheat and inter pas temperamental during PQR, so there is no issue to write down both in your WPS.but you cant any change in PQR.

Subject: [MW:13460] amendment for this WPS regarding
From: kvnkat@rediffmail.com

Dear All,

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.
