6g Weld Test on 2 inch Schedule 80 pipe - TIG root, fill, & cap
This is a 6g weld test on 2 inch schedule 80 pipe.
This particular test is TIG all the way out. Root, fill, and cap all done with ER70S6 1/8" filler wire.
My friend Andrew Cardin shows us the freehand technique on a 6g pipe test.
If you have ever tried a test like this before, you know that it gets pretty hot before you get finished.

The 6G weld test is a performance qualification test that assesses a welder's ability to create a sound weld on a pipe in the 6G position. This position is considered the most difficult as the pipe is fixed at a 45-degree angle, requiring the welder to either switch hands or at least get uncomfortable to move around the pipe while maintaining a consistent weld.
Passing a 6G weld test for TIG welding carbon steel pipe is a big deal for any welder looking to advance their career and often means a better paycheck.
A 6G test requires body positioning, good technique, and knowledge of the welding process.
