Welding Thin Metal Sheets

Mig welding for thin metal mig is one of the best ways to weld 20 gauge sheet metal.

Welding thin metal sheets. Mig welding is one of the simplest to use for welding. 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. The aim with this technique is to melt a bit of metal and then let it cool slightly before melting the next and it s a handy way to avoid blowing holes. Spot welding is usually used to join a panel of overlapping sheet metal parts that are usually 3mm thick.

The spot welding process is one of the oldest welding methods used. Gas metal arc welding gmaw is an effective method for joining light gauge metals such as carbon steel and austenitic stainless steel. It is an arc welding process that where you feed a solid wire electrode through a welding gun. Minimizing burn through and distortion is essential to obtaining a good weld when gas metal arc welding thin gauge materials.

The ration of thickness should not exceed 3 1mm.
