The refers to an advanced pipe welding position where the pipe is fixed at a 45-degree angle . Widely considered the most challenging position to master, it requires a welder to demonstrate proficiency in four primary orientations—flat, horizontal, vertical, and overhead—within a single continuous pass.
The test usually involves two pieces of pipe (commonly 6-inch schedule 80 or similar). The ends are beveled to create a "V" groove when placed together. 6g welding process
The 6G position forces the welder to constantly adapt to changing gravity effects. The weld pool behaves differently at every clock position: The refers to an advanced pipe welding position
