Re: Downhand pipe welding with 6010

Well, I saw some 1/2" wall 48" being welded downhand the other day. Pipe is 1/2" wall internally and externally coated carbon steel. The largest I've ever seen done downhand. I think they are using the local equivalent of 6010 downhand. There is no way to spin the pipe as they are ass...

Re: Downhand pipe welding with 6010

The 6g position test video used TIG for root. This means different position and different process. Interesting, video, but does not answer the requested specs in the original post. Thx My link takes you right to a 6g, 6inch, 6010 pipe test, not the specs you were describing though. :arrow: John Yes...

Re: Downhand pipe welding with 6010

Believe it or not, the pipe is almost standard 3" & 4" gathering line for oil and gas wells in North America. The line is rated for a maximum operating pressure of 1000 psi if I recall correctly. Most pipe like that is jacketed with a plastic coating over a thin tar base. The ends of t...

Downhand pipe welding with 6010

Hi Jody I have seen a lot of line pipe welded downhand using 6010 5P. The pipe is typically relatively thin 1/8" wall material - pretty close to structural steel. Typical is a very narrow open root done with a smaller rod and a single hot/cover pass with 1/8" rod. The resulting weld is abo...
