RE: A 358 pipe by SAW process
Based on your post, you will need to do the following;
1. Qualify a welding procedure using this welding process and following the requirements in ASME B&PV Code, Section IX for P-No 8 base material.
2. Welder will also need to be qualified, per Section IX.
2. Review ASME B&PV Code, Section II, Part C, AWS SFA filler metal specification for the SAW process. There is plenty of information to choose from to select an appropiate filler wire and flux combination. Also, check with your current filler metal supplier for additional information.
