: Align the pipes using a heavy-duty angle iron or a specialized pipe fit-up clamp to hold them steady and square.
The 1G position, where the pipe is rotated, is the baseline, allowing for a flat weld which is the easiest to execute. However, the true test of a pipe welder lies in the fixed positions. In 2G, the pipe is fixed vertically, requiring horizontal welding—a test of side-to-side manipulation. In 5G, the pipe is fixed horizontally, forcing the welder to transition from flat welding at the top, through vertical-down or vertical-up on the sides, to overhead welding at the bottom, all within a single circumference. The apex of this discipline is the 6G position, where the pipe is fixed at a 45-degree angle. This position is the industry standard for certification because it encompasses every possible gravitational challenge—flat, horizontal, vertical, and overhead—simultaneously. Mastering the 6G position signifies that a welder possesses the versatility to weld in any field condition. pipe position welding

In 5G and 6G, use a "stitch" or "whip" technique for stick welding (SMAW) to let the puddle freeze before moving. In 2G, the pipe is fixed vertically, requiring
