Technical Field

The invention relates to a processing instrument, in particular to a special welding gun.

Background

With the continuous development of society and the increasing shortage of energy, people put forward higher performance requirements on various industrial products, which not only require good ductility and higher bearing strength, but also require green safety and energy saving, so that the quality of the industrial products needs to be greatly reduced. In inert gas shielded arc welding using pure tungsten or activated tungsten (thoriated tungsten, cerium tungsten, zirconium tungsten, lanthanum tungsten) as a non-melting electrode, a metal is melted by an arc between the tungsten electrode and a workpiece to form a weld bead. The tungsten electrode is not melted in the welding process and only plays the role of the electrode. While argon or helium is fed from the nozzle of the torch for shielding. Metals may be additionally added as required. Internationally known as TIG welding.
