Hi guys, I’ve been working for a distribution natural gas company for twenty years and been pipe welding for fifteen of those years. My welding procedures calls for 6010 series welding (downhill) and my colleagues and I do our annual 12” branch and butt fuses. Our local state regulatory agency wants to get away from the 6010/7010 series rod due the inherent defects/problems that can arise from its use; I honestly and my colleagues feel this is hogwash and not too happy with this and is definitely another post that we can visit another time. The reason of my post is has anyone ever heard of a welding qualification that calls for a 12” vessel ( pipe) filled with water and the branch test is performed using 7016 uphill root and hot pass with 7018 fill and cap? If so what is the name of that test? Also a second water filled vessel (12” pipe) and a 12” split sleeve longitude fill and circumference welds. I can’t seem to find any info on this. I see a lot of info on the branch and butt welds that my welding teammates complete every year but nothing like what I previously explained. My welding supervisor also wants us to circulate the water through the two pipe vessels via a small water pump! We are very fustrated and looking for some input and guidance. Thanks again!
