The surface of the crusher wear plate is easily oxidized, and the interface is oxidized to reduce the bonding strength of the interface. And for the crusher wear plate that has higher requirements on the quality of the plate, during the heating process, the appearance of oxidation decarburization and the burning loss of alloy elements will reduce the appearance of the crusher wear plate. In order to solve the problem, surfacing welding can be used.

Surfacing welding is to use the chromium carbide wear-resistant surfacing welding wire to metallurgically weld the welding wire on the appearance of low-carbon steel through a fully active wear plate surfacing welding machine, or it can also be double-sided. The wear plate of the crusher adopts the open-arc fully active surfacing process, and a layer of high-alloy wear-resistant layer with high hardness and high wear resistance is surfacing on the appearance of the ordinary steel plate or stainless steel plate. Metal properties, ie high wear resistance of the working layer and high plastic toughness of the base layer. It provides convenient mechanical connection and electrode connection conditions for industrial applications, and can realize processing such as reeling, welding, plasma cutting, and mechanical connection.
