Hi there,
We have a situation, our Valve contractor want to weld jachket material which is plate stainless steel TP316 Eurpian standard to LTCS cast material ASTM A 352 LCB standard. The reference welding code will be Europian standard. We asked for WPS, and they provide us WPS for CS to CS material, & SS to SS material acomponied by PQR, but WPS for LTCS to SS material. We asked for LTCS to SS material WPS and PQR, and they replied that within Europian standard they never used such WPS. My quesion is, "Is this answer is acceptable?", what I know according to ASME Sec IX, for wach welding type we should have exact WPS and PQR, otherwise is not acceptable.
Could you please help me on this.
Thanks & Regards,
Parviz
