How to Perform Sheet Metal Work on Aluminum Car Bodies?
2 Answers
Use a flame torch to heat the car body, softening the aluminum alloy body to facilitate better pulling. Once the dented area is softened, pulling work can be performed, accompanied by hammering during the pulling process. After repairing the dented area, use a file and a grinder to smooth out the surface, ensuring it is even.
I had a dent in my aluminum car body before, and I thought regular tools would do the trick, but it turned out to be really tough. Aluminum is soft and can't be handled as roughly as steel; you need tools specifically designed for aluminum, otherwise it's prone to cracking. First, I cleaned the damaged area and bought an aluminum body repair kit online, which included pry bars and a plastic hammer. I gently tapped the dent, being careful not to use too much force to avoid deformation. After reshaping, I had to carefully sand it down. Welding was even harder—aluminum has a low melting point and requires low-heat welding. I tried but failed, so I borrowed a TIG welder from a friend to fix it. The whole process requires patience. Finally, I applied anti-rust paint to protect the repaired spot from corrosion. Honestly, small dents can be DIYed, but for bigger ones, I'd recommend going to a professional shop. Aluminum is tricky to work with, and if not done properly, it can compromise the car's structural safety.
