Tig Welding Thin Sheet Metal

Best tips for tig welding sheet metal 1.

Tig welding thin sheet metal.

Apply the right foot pedal control and power setting. This technique is ideal for welding metals that have at least six millimeters of thickness. Tig welding for sheet metal using a tig welders means that one can work on materials of 26 gauge. 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.

The diameters down to 020 040 and 1 16 inch tungsten are popular. 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. To prevent warping and burn through then try not to whip or weave the torch. Use the 1 for 1 rule whenever you re welding thin metals.

Ceriated tungsten are preferred with thoriated tungsten as a second option. However you must tune the tig machine to the best settings before using it to weld thin sheet metals. Using this process enables more than effective work on thin materials as it provides high precision and high quality work.
