An excellent way to transition to pipe welding is to weld plate first.
As long as thickness, bevel angle, gap, and land are the same, the same settings work on pipe so it makes sense to establish settings on plates
Sometimes welding procedures specify downhill root and other times uphill is specified. It is great to be able to do both so you will be ready either way.
uphill root voltage and wire settings are a bit lower but is really not more difficult than downhill once you nail the settings
One Simple MIG Welding Technique That works for All Positions
Can one Technique work for all positions?
This simple technique basically just traces the front edge of the puddle where the rubber meets the road. But Cut and Etch testing is still one of the best ways to verify your technique and settings
