Linear Archetype Joint

I learned that with welding with TIG on aluminum that if you bump the electrode and the fillet wire together it could mess up you current weld or the plate itself. When welding on aluminum while doing a tee joint its important to have the right arc length, torch angle, and amperage. Also I learned that when welding an aluminum tee joint it good to keep the beads small and get the puddle to flow into the corners.
