Pipe — Position Welding

Like 1G, the pipe is horizontal, but it is fixed in place. The welder must move around the pipe, performing a combination of overhead, vertical, and flat welding to complete the joint.

To put together two pieces of pipe, you follow a process called , which ensures the pieces are aligned and ready for a strong, consistent weld. Here is the step-by-step breakdown: 1. Preparation & Cleaning Like 1G, the pipe is horizontal, but it is fixed in place

The "art" of pipe position welding is found in the manual manipulation of the electrode or torch. The welder employs specific weave patterns—crescent, zigzag, or "C" patterns—not merely for aesthetics, but to manage the heat input and direct the molten metal into the crevices of the joint. Here is the step-by-step breakdown: 1

If you only practice rolled welds, you are a bench welder. If you practice 6G with a mirror behind the pipe, you are a pipe welder.

Pipe position welding is a specialized field of metal joining used to connect pipes in critical infrastructure like oil and gas pipelines, water systems, and power plants. Unlike flat plate welding, pipe welding often requires the technician to navigate curved surfaces and maintain consistent weld quality while the workpiece remains fixed in a specific orientation.
