The position is defined by a code: .
Look at any refinery, power plant, or skyscraper. The straight, horizontal pipes you see at eye level were likely welded in the position. The vertical pipes bolted to concrete were 2G . But the pipes in the crowded, hard-to-reach corners—the ones carrying high pressure or nuclear steam? Those were welded in 5G or 6G by a master tradesperson who learned to fight gravity one inch at a time. weld positions pipe
As you weld, the pipe is rotated so the weld puddle remains in the "flat" or "downhand" position. The position is defined by a code:
If you are setting up an upcoming qualification test, let me know the (SMAW, GTAW, GMAW) and the pipe material you plan to use so I can provide specific parameters. The vertical pipes bolted to concrete were 2G
In the world of pipe welding, your position is everything. Whether you are working on a cross-country pipeline or a tight refinery manifold, the orientation of the pipe dictates your technique, your safety, and the ultimate strength of the joint.
