Sometimes when you are out of practice, its good to just practice until things feel natural again. I welded a 3g butt on 11ga aluminum and the first try did not go so well, so I settled in and just stacked a few beads on scrap until things felt more natural and comfortable
This Video gives tips for TIG welding a 1G flat butt joint and how to watch the puddle sink to make sure you are getting penetration,
A tee joint fillet weld test in 11 ga thickness usually requires penetration into the root but not all the way thru the back side
The outside corner joint is a very common one. This video shows a slightly different perspective using aluminum angle. Same joint, different perspectives and some practice padding beads added.
This project was sent to me by a laser cutting company that sells them as weldable kits. It was a good practice project that required a lot of different torch angles. Rotating the torch head as you weld is shown along with plenty of instructive arc shots
