Classification of plasma arc surfacing

       

According to different filling methods of filling materials, plasma surfacing can be divided into: 1: Cold wire plasma surfacing, plasma surfacing machine Cold wire plasma surfacing uses welding wire as a filler material, and is directly fed into the welding area for surfacing without preheating. 2: Hot wire plasma surfacing, valve surfacing machine Hot wire plasma surfacing is to use the resistance of the welding wire itself for preheating, and then send it into the plasma area for surfacing welding, and can use single wire or double wire feeding. 3: Prefabricated plasma surfacing, wear-resistant surfacing equipment Prefabricated plasma surfacing is to prefabricate surfacing alloy into a certain shape and place it on the surface to be surfacing, and then melt it with plasma to form a surfacing layer. 4: Powder plasma surfacing, plasma spray welding machine Powder plasma surfacing is a surfacing method in which alloy powder is fed into the plasma arc zone and melted to obtain a surfacing layer. Most alloys can be made into powders, so the source of materials for powder plasma surfacing is very convenient, and is not limited by the ductility of the material like wires. The alloy powders commonly used in powder plasma arc surfacing mainly include self-fluxing alloy powders. And composite powder.
