Tig Welding Thin Sheet Metal

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.

Tig welding thin sheet metal.

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. Using this process enables more than effective work on thin materials as it provides high precision and high quality work. Unlike the mig welding process the tig welding technique offers clean and strong welds. But using this method also requires some practice and practice advice in order to understand it.

Apply the right foot pedal control and power setting. Best tips for tig welding sheet metal 1. Ceriated tungsten are preferred with thoriated tungsten as a second option. This technique is ideal for welding metals that have at least six millimeters of thickness.

Tig welding sheet metal forget the larger 1 8 inch tungsten electrode and use a smaller one. To prevent warping and burn through then try not to whip or weave the torch. The diameters down to 020 040 and 1 16 inch tungsten are popular.
