Dear Experts,  Good day to you all! IF I make a PQR with 6G position,  1- Can I prepare a WPS for 4G position & 6G position as well?  2- 4G and 6G must be separate WPS's or it can be in same WPS? And Can I prepare an ASME WPS with the same AWS D1.1 PQR if I cover all ESSENTIAL Variables? If YES, I can cover all the required Mech Testings as per requirements of ASME. If anyone has a sample please share it as a reference.(PWPS, PQR, WPS- Material P1, SMAW process) regards raj

Dear Jamie, WPS/PQR/WPQ was qualified in accordance with AWS D1.1 Yes the testing was done at an accredited third party lab and we have the test certificates from the lab stating that the PQR was used to qualify the welders.
