TIG Welders Work For Creating Arc Weld

TIG welders work for creating an arc between a metal to be bonded and a tungsten electrode. The arc creates the weld, while gas fed through a torch seals off the welded area and protects it from the atmosphere and other conditions that might affect the weld involves a lot of heat and electric current, so it is very bright and requires the use of a welding shield.

TIG welding uses tungsten electrodes dissolve during the weld. TIG uses a filament that burns away after the weld is complete. Each can use a filler rod or steel. TIG welders classically can use no filler bar at all to bond two pieces of thin metal together, while they use long filler rods for thicker metals. The rods are fed into the weld to fill the gap during torch provides the seal for weld.

TIG welding is very high superiority and measured one of the best welds in industry work. Students need to understand how the gas acts must control the movement of the torch and filler very carefully. TIG welders use argon gas, combination of helium and argon. It used to be performed using helium gas only, when it was invented in the 1940s but argon gas proved to be more efficient and is the most common gas used today.
