Tig Welding Thin Sheet Metal

This technique is ideal for welding metals that have at least six millimeters of thickness.

Tig welding thin sheet metal.

Tig welding sheet metal forget the larger 1 8 inch tungsten electrode and use a smaller one. Best tips for tig welding sheet metal 1. Use the 1 for 1 rule whenever you re welding thin metals. The diameters down to 020 040 and 1 16 inch tungsten are popular.

However you must tune the tig machine to the best settings before using it to weld thin sheet metals. Ceriated tungsten are preferred with thoriated tungsten as a second option. When estimated the heat input that is required for your project use the rule that 1 amp should be used for every one thousandth of an inch of thickness for your metal. Apply the right foot pedal control and power setting.

When you are welding thin sheet metal with any welder either it is tig or mig the primary purpose is to avoid the sheet from burn through warping and extreme heat affected area while still assuring the weld has sufficient mechanical capacity for the application. But using this method also requires some practice and practice advice in order to understand it. Using this process enables more than effective work on thin materials as it provides high precision and high quality work.
