Plasma Welding Machine is special purpose machine for engine valve. It is used for welding seat face and tip end, which is conducive to the formation of a good weld quality.
During the welding process of the plasma welding machine, the plasma flow penetrates the molten pool to form small holes. Under the action of surface tension, the molten pool metal flows to the tail of the molten pool along the small hole. When the arc moves forward, the molten pool crystallizes to form a weld, which is conducive to the formation of a good weld quality.
Plasma welding machine applications include: surface welding, spraying and welding. By using low pulse welding current with adjustable frequency, plasma welding can control the arc energy in a better way, which is a high-quality welding method. The depth/width ratio of the weld is large, the heat-affected zone is narrow, the deformation of the workpiece is small, and there are many types of weldable materials.
