The wire speed should be between 7 to 9, depending on the thickness of the sheet metal. . Tack-welding the metal first will allow you to hold and align each workpiece before the full-blown . The weld initially looks bad because of the slag from flux core welding. Spatter. Tiny beads of metal also get left behind after flux core welding which can create more grinding work. Porosity. You’ll get tiny holes or pockets of contamination in your weld. Blow out. This is when your sheet metal literally blows out the sheet metal into . On thicker material, you don’t need to worry about this much, as it doesn’t react as easily. Sheet metal is a different story entirely. Sheet metal is typically used for panels where being straight is important. Rocker panels, floor pans, patch panels, the straighter the better. Point being, the key to straight panels is heat mitigation.
However, getting the MIG welder’s settings just right is key to a successful weld. For filler metal selection, the electrodes in the ER4xxx and ER5xxx are most suitable for welding auto body panels.

8.1 Considerations for TIG welding; 9 Sheet Metal Part Design for Manufacturing Tip. 9.1 CORNERS AND WELDING; 10 Sheet Metal Fabrication Welding FAQ. 10.0.1 What are the key welding methods used by fabricators? 10.0.2 What is the difference between spot welding and tack welding? 10.0.3 When should fuse welding be used, and what materials are . Hey everyone, new to this board and have a newbie question. I am welding on an automobile project and having a little trouble. I am welding in some 16 guage sheetmetal to change the contour of the inner fenders, and the sheetmetal in the car is probably 18-20 guage. The problem I'm having is welding the 2 pieces together, I am blowing through the thinner stuff . 3. Adjust Your Torch Angle. Changing the torch angle when MIG welding goes a long way to preventing burn-throughs. Make sure you adjust the angle to shorten the distance between the tip and the metal, no matter the welding position you work in.This will make the arc more stable, giving you more control over the weld and lessening the chance of burn-through.
Most of the light gauge sheet metal work will require the use of .023- or .24- inch while if you have a sheet metal having a gauge of more than 18-gauge then a .030-inch wire would be the most ideal. A ER70S-6 wire would be most ideal for welding mild steel.
A welder with a wire feed speed of 50-200 inches per minute is suitable enough for thin metal sheets, but the specific settings will depend on the actual thickness of the sheet you will be welding.
