[0002] Plasma arc welding refers to a fusion welding method that uses a high energy density beam of plasma arc as a welding heat source. Plasma arc welding has the characteristics of concentrated energy, high productivity, fast welding speed, small stress and deformation, stable arc, and is suitable for welding thin plates and box materials. It is particularly suitable for welding various refractory, easily oxidized and heat-sensitive metal materials (such as tungsten, molybdenum, copper, nickel, titanium, etc.). The gas is heated by the arc to produce dissociation, and is compressed when passing through the water-cooled nozzle at high speed, increasing the energy density and dissociation degree to form a plasma arc. Its stability, calorific value and temperature are higher than those of ordinary arcs, so it has greater penetration and welding speed. The gas that forms the plasma arc and the protective gas around it are generally pure argon. According to the material properties of various workpieces, helium, nitrogen, argon or a mixture of the two are also used.

[0003] The existing plasma arc spray welding nickel-based welding auxiliary structure requires manual pushing of the nickel-based rods back and forth during the welding process. Manual handling is time-consuming and laborious, and the surface temperature of the welding is high, which can easily burn the arms, thereby causing inconvenience in the use of welding and reducing the use efficiency of the device.
