Additional WPS/PQR Questions: 1. If a welder qualifies on GTAW P-1 to P-1 using ER70S-2 and qualifies on SMAW P-1 to P-1 using E8018-C3, would he automatically qualify on a GTAW/SMAW P-1 to P-1 using ER70S-2 root/E8010-C3 cover? 2. If a welder qualifies on SMAW P-1 to P-1 using E6010/E7018...

Thanks Kiwi2671!

Hello again. I have a question regarding the use of backing rings. If the welder qualified on 2" dia. sch. 80 pipe (SA-106) using 6010/7018 w/o backing, would he have to re-qualify if backing is used? No changes to any other variables. It seems that on the WPQ under the column "Range Qualified"...

stanweld & weldtek, I thought that may be the case, but it's nice to get verification. Thanks again for your assistance.

stanweld, Regarding the PQR is it true that whenever a new WPS/PQR is written, a sample must be lab tested and documented (tensile & guided bend)? A weld inspector told be that each PQR had to be independently tested. This can be quite costly, esp. if there are multiple PQR's.

Thank you stanweld & metengr for the help.

stanweld, So,in review: In addition to writing a new WPS & new supporting PQR, the welder who is currently qualified using 6010/7018 will NOT have to test using 7010/8018? Sorry if this seems redundant - just trying to get it right! Thanks.

Thanks, metengr. All variables remain the same except for the change in electrodes. So, if I understand correctly, I'll write a new WPS & supporting PQR - WPQ. I appreciate the help.

stanweld, Thank you for the prompt reply! We'll be using a E7010-A1 & E8018-C3. Since I'm relatively new to this, would you mind explaining what is meant by "the WPS must be requalified"? Would you happen to know the applicable section in code?

Hello all. I'm new to this forum and would like your help with a welding issue. Question #1. If a welder has done performance qualifications for SMAW for the following: P1 to P1 with F-3 & F-4, currently using 6010 root/7018 cover, would he also qualify for 7010/8018 (all other variables are...
