Pipeline Welding Techniques
Pipeline Welding Techniques
(OP)
Good morning,
I am working with piping company which specialized on only aboveground pipeworks. And there is an upcoming pipeline work that we will possible get awarded.
Our old procedures are outdated, could anyone explain me current pipeline works. I mean is 2-3 group stick SMAW welding still popular?
Should we do Argon GTAW root and then SMAW fill? Work is roughly 100km, will full SMAW be faster? Or is it not worth it due to the better root result with GTAW root.
Thanks,

In my humble opinion, you should start by reading this textbook for beginners: http://www.kobelco.co.jp/english/welding/events/fi...
By the way, in your company, what part of the work are you involved with?

It's true that GTAW gives good root but if you prefer higher productivity you can switch to GMAW-STT that is a type of GMAW process with which root can be effectively welded. Please have a look at this link: GMAW-STT (Surface Tension Transfer) for CS
