My current concern is how I am going to paint it. As I understand it, I should: Remove any rust and mill scale with a stripping pad on my angle grinder (I will do this before welding) As much as I would really love to just put a whole new tub on it, I just don't have the time or the space to do so. So that leaves me with doing patch panels to fix the issues. Now, that being said, most of my welding experience is with thicker materials. Bumpers, roll cages, tube fenders, etc. I really haven't done much sheet metal work.
Use thin wire-One big mistake we see with beginners is using welding wire that is too thick for the metal they’re welding. If your welding wire is too thick it will take more heat to melt the wire than the substrate and can make it even more prone to blowing holes in the panel. For thinner gauge sheet metal like 18 or 20 gauge we suggest .023 . Imagine a welding process that minimizes distortion, enhances precision, and improves efficiency. Laser welding technology for sheet metal does exactly that, revolutionizing industries from automotive to high-tech electronics. This article explores the advantages of laser welding over traditional methods, detailing its superior heat control, speed, and flexibility. .
For a strong weld on painted metal, the weld first needs to penetrate the paint layer and have a deep enough melt onto the metal surface. That’s why selecting the right welding rod matters a lot. For painted surfaces, good general advice is to choose 6010 or 6011 welding rods.
I was not paying attention to the thickness of sheet you were specifying .9 of a mm is equivalent to 20gauge sheet metal. In normal industrial practice it is more common to put a spot welded tab flange with a sealant, rather than a weld. If you insist on torch welding this part (TIG) heliarc is recommended. Overlapping is the absolute wrong way to do it and butt welding is the only quality way to do it. if you overlap then you are wasting your time because you are doing nothing but inviting rust back into you panels for the future. Take the time to learn to butt weld an do it right or stop doing metal work. Theres no in between.
Here Are Some Work Arounds You Can Do With Painted Metals. First, you can use a method called spot welding, where you only weld a specific spot on the metal rather than a larger surface. To do this, you will need: two copper alloy electrodes; two sheets of metal; The electrodes will heat up and weld the specific spot between the two sheets of metal. This method won’t work .

Do you need to remove paint from metal before welding? If you are repairing a broken weld, grind the old weld off completely. Then, remove any paint and clean up the edges, so the mating surfaces fit evenly. This is preferable to trying to weld over the broken area. Your new weld will be stronger and look more professional.
