Mig Welding Thin Sheet Metal

Tips for welding sheet metal and body panels with mig.

Mig welding thin sheet metal.

The two most commonly used methods for welding sheet metal are mig and tig methods. Mig welding is one of the most appropriate methods used for sheet metal. Fit up and joint design. The effect is quite neat though this is a cold method of mig welding.

However in some cases spot welding is also utilized. If you are just starting with mig welding it can be quite tough to weld delicate materials so at first better start welding thicker metals that give you more room for error. Keep the stick out short stickout of your mig wire is important when welding any type of metal but especially sheet metal. Holding the tip too far from the surface will cause the wire to have to come out too far to touch the metal.

This method is favorable as it leaves room for beginners to practice and get better. When welding thin metal the main objective is to avoid warping burn through and excessive heat affected zones while still ensuring the weld has enough mechanical strength for the application. When it comes to welding thin sheet metal like car body panels if you are not experienced and skilled enough then you can easily create a mess as blow holes in the sheet and make the metal useless. The steel is 0 8mm thick and the welder power was set to minimum.
