Welding Positions 1G, 2G, 3G, 4G, 5G and 6G Explained

What each welding position means and why 6G is the benchmark qualification.

1G is flat, 2G horizontal, 3G vertical and 4G overhead for plate. For pipe, 5G is a fixed horizontal pipe and 6G is a pipe fixed at 45 degrees, which requires welding in every position around the joint. Passing a 6G test usually qualifies a welder for all positions.
