To fix warped sheet metal after welding, you can follow a few steps. Firstly, use a torch or flame to heat the warped area of the sheet metal. Once heated, rapidly cool the area with water or compressed air to help reposition the metal. Next, combine excessive heating with hammering or striking the sheet metal in the opposite direction of the warp.
