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.

Spot welding is usually used to join a panel of overlapping sheet metal parts that are usually 3mm thick. The thin metal technique is a non continuous process that is used for thin metal such as car body panels. 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. Its primary usage is in welding auto body and sheet metal.

Gas metal arc welding gmaw is an effective method for joining light gauge metals such as carbon steel and austenitic stainless steel. Minimizing burn through and distortion is essential to obtaining a good weld when gas metal arc welding thin gauge materials. The spot welding process is one of the oldest welding methods used. The ration of thickness should not exceed 3 1mm.
