Pipe Welding: 6G TIG Root Pass
What you will learn in this episode:
In this episode of TIG Time we are back at Cowley County College with Welding Instructor, Bob Moffatt. We have had many requests for a demonstration of welding pipe in the 6G position, so that's exactly what we are going to show you. Sit back!
What is 6G?
6G welding of pipe refers to the angle at which the pipe is fixed at a 45Â° (+/- 5Â°) and is not rotated. 6G pipe welding is one of the most sought after certifications, because If the welder qualifies in this position they are generally qualified for everything else (1G, 2G, 3G, 4G, 5G, and 6G). Also depending on code and company specification often times when a welder is qualified for 6G they pre-qualify for fillet welds in certain positions.
The 6GR position has the same incline of 45 degrees as above, however it has a restriction ring around the pipe. This is used to simulate real world environments where access to the weld joint is not always easy. Some examples of this include T-, K-, and Y- connections.
