Best way to weld sheet metal panels.

Ditch a 1 8 inch tungsten electrode for something much smaller like 1 16 inch tungsten. Time will tell just how well it holds up. Butt welded panels withstand stress better than any other type of weld joint. The best way to estimate the heat input needed for welding is by applying the 1 for 1 rule.

The best way to weld sheet metal panels together is by butt welding which is joining them side by side see picture below. How to weld thin metal the thin metal technique is a non continuous process that is used for thin metal such as car body panels.
