Tig root pass on carbon steel pipe Miller Welding much faster Tig root pass on carbon steel pipe Miller Welding Why do Welders use root pass on pipe?Why do Welders use root pass on pipe?This provides less chance of cold lap or lack of fusion, less spatter and a higher quality root pass on pipe. The stability of the weld process lessens the weld puddle manipulation required by the welder and is more tolerant to hi-lo conditions, reducing training requirements.RMD/Root Pass TECHNIQUES - Welding Equipment Where to place welding torch in root pass weld?Where to place welding torch in root pass weld?Welding (5G) If the pipe is rotated in the 1G position, the torch should be positioned off the top center of the pipe at the (1:00-2:00) position. Positioning the torch directly at the top of the pipe results in excessive penetration and inconsistent burn through. 12:00 Welding (1G)STT Pipe Root Pass Weld Process Guide - Lincoln Electric

When to run Tig roots on stainless steel?When to run Tig roots on stainless steel?I like to run tig roots like this when I'm doing rollouts (especially on stainless), gravity makes it even easier.

fabricated pipe spools for oil and gas movement. Welding operators are able to complete MIG, TIG and Flux-Cored welding , mostly Schedule 40 and Schedule 80 carbon steel pipe and some low tin and Schedule 10 stainless steel . USA Energy Fabrications high level of productivity and consistent, code-quality welds are driving factors in the Tig vs Stick, which is faster - Weld Talk Message BoardsI think a lot will depend on the pipe diameter as well as joint configuration. If everything is just a socket weld then stick it. Stick welding butt joints (6010 root and then grind and low-hi cap) on anything smaller than 4" sch. 40 just isn't much fun so those I would prefer to tig in any case.

Tig Root - Weld Talk Message Boards

Carbon steel isn't too bad, but some other metals will suckback worse. As for the hotpass, I run 2 beads, trying to stay on the sidewall of the pipe a little, and 1/2way across my root , and don't stay there too long, or you will burn through. I keep a very small amt of drag angle on my electrode, that will help with burnthru/meltthru, too.

Nitrogen Purging of CS pipe for TIG - WeldingWeb

You do not need to purge the inside of carbon steel pipe when tig welding your root with 70S-2 filler. It is not like tig welding stainless pipe where purging is required to prevent sugaring/porosity issues. Purging carbon steel pipe just adds to the time and cost of the welding job. IMO. How to Tig Weld with the Lay Wire TechniqueIts not always the best way to tig weld but it works really well for certain things and on certain metals. Stainless steel pipe and carbon steel pipe are both good candidates for using the lay wire technique.
