Pipe welders only know how to weld in circles
Joking of course..
I would add there is some missing information. D1.1 is just a structural code. You want someone who's D1.1 4G certified. Welders need to re-certify yearly, so make sure they're current. 4G just grove weld in the vertical position. That qualifies you for flat (1), horizontal (2) and overhead (4) and vertical (3).
Types of Welding Positions, 1G, 2G, 3G, 4G, 5G, 6G/6GR Joint Types
Know all types of welding positions and joint types. It reveals four welding positions and joint types such as 1G, 2G, 3G, 4G, 5G and 6G/6GR.www.weldinginfo.org
In short +1 to bb29510s comment, you want someone under a company for insurance reasons, not a rig welder side job.
4G is overhead position, 3G is vertical position. Under D1.1 code, 4G does not qualify for vertical welding, just flat and overhead grooves and flat, horizontal and overhead fillets.
