i am wanting to take my weld test for 6G on pipe the question i have is do i have to do it up hill or down hill in all the books i have read i can not find this awnser hopefully some on can help
Reply:mine were all uphill, but that was for sch 80 pipe, and that is what the company wanted. i think downhill is for sch. 40 and below, i am not sure.
Reply:There probably is a welding procedure and you must follow it. JohnSMAW,GMAW,FCAW,GTAW,SAW,PAC/PAW/OFCand Shielding Gases. There all here. :
Reply:The Lincoln Procedure Handbook Of Arc Welding should cover it. The only one I remember for sure is ASME Code 9-G6. It calls for a downhill stringer with 6010 and then uphill with 7018 the last time I took it which has been a few years ago. Ah, the joys of retirement. Oh, I forgot, that is on 6" sch. 80 pipe on a 45 degree angle. Dunno about sch. 40.
Reply:When I took my test, I had to use P5 downhill for the root then 7018 uphill the rest of the way. Boo
Reply:my test was sch.80 6" open root 6g all up. root and a hot 6010. cover and cap 7018. hope that help's. that test was for united states steel.

Reply:thank you all i appreciate the advice and help ill let yall know how it goes
Reply:I am working ,on a 6 in. sch. 40 test, for the pipefitters, right now and it is uphill. The root is 6010, the hot pass and cap are 7018.
Reply:Uphill.Anything can be fabricated on-site. Truth is fabricated online.
Reply:It depends on the required procedure and that will be supplied by the company. I have done the ASME Code 9 G6 on sked 80 6" numerous times sometimes they want the root and hotpass uphill, other times it's downhill. It depends on the company's specified procedure.The difference between art and craft is the quality of the workmanship. I am an artist. |
