Hey, all,
I took a basic welding course in the community college but I'm not in it anymore.
At home I want to try practicing a 6G weld (with tig root and tig fill) on some scrap 3" pipe.
Are there any pipe welders out there who could tell me what would be common, or typical, parameters to use on a piece of 3" pipe with a wall thickness of .208" in a 6G test? (I've never really taken any welding tests.)
For example, what bevel angle?
How big of a land?
How big a gap?
What amperage? (I plan to use lift-arc with no pedal or hand throttle.)
What size filler?
Any tips on figuring out how high to position it, since I can't move it after I've started welding?
Also, should I weld uphill or downhill on the sides of the pipe? Does ASME have a preference? (My CC course was in structural stick welding, and all our welding was uphill.)
Anything else I should be asking, but don't have the sense to ask?
Thanks in advance for any advice for the new dummy.
