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 -- To post to this group, send email to materials-welding@googlegroups.com To unsubscribe from this group, send email to materials-welding-unsubscribe@googlegroups.com For more options, visit this group's bolg at http://materials-welding.blogspot.com/ The views expressed/exchnaged in this group are members personel views and meant for educational purposes only, Users must take their own decisions w.r.t. applicable code/standard/contract documents.
