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.

Andrew uses a TIG finger to prop on this 6g weld test so he can focus on the weld without being distracted by his knuckles burning.

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.
