Heat up cool down repeat with this technique tack welds are applied along the seam with plenty of space in between. Our copper weld backers help to keep a welds from blowing through the metal and also act as a heat sink. How to prep panels to achieve the perfect butt weld using eastwood s perfect panel prep tool.
