I'm the new guy on the block. I was an R stamp welder for a boiler company. I can pass a 6G stick. I finished welding a 2.5" natual gas line for a mechanical company. They are going to test it with 100lbs of air presure, then spy for leaks. I feel confident but you never now. Most of the welding done in 5G position was done on a 20 foot ladder. I learned you can roll it with chain grips, weld it in posion while the pipe in in the hangars (9:00 to 12:00) roll it, Then slide each section down. I had about 7-8 welds this way then the prefab was on the ground. I had 2 5G in paosion welds in the ladder it was far from the walls. I was in brefore the framers so it was pretty smooth. Any tips for faster speed and quality insurace are greatly apperacited. Thanks....
