Tack welds are simply small welds that barely penetrate the metal and aren’t pushed or pulled to form a bead. Tack weld different areas of the joint about an inch apart. This will hold it in place and allow you to weld it properly.
Why do you need to let tack welds cool off?
You need to let it cool because overheating is very common when repairing body panels, which leads to warping. If your sheet metal is thin then you’ll have to be extremely careful.
How to cut rust out of metal?
A plasma cutter is my favorite tool for cutting metal. Start by identifying all the areas that contain rust and mark the area that you’re going to cut out with a pen. To keep the structural stability in the metal you’ll want to leave as much of the original metal as you can, but you still need to cut out all the rust. If you leave rust it could spread and ruin all your hard work. When you mark out the area to cut out, remember that basic shapes with straight lines will be much easier to replace and cut out than ones with curves or many sides.
