I have a client that has sub-contracted a small fabrication shop to build some piping spools IAW B31.3 , the fabrication shop currently has only handled API 1104 fabrication and does not have any welding procedures and the client has agreed to supply them with the procedures to use. We are welding all P1 G1 material ( SA-106 , X52 and A333 Gr 6 ) , the clients "welding guy" has given the fabricator for SAW and SMAW process are both qualified with P1 G3 material ( SA-516 ). I did a very quick review for my own benefit and do not think they can use these procedures being that they are Group 3 and not a group 1 or 2. Can anyone shed some insight as to if I am on the right track ? I confuse myself sometimes when reading ASME Sec IX versus what I am more accustomed to ( API 1104 ). Thanks in advance for any insight.
