Surfacing welding rod

Surfacing welding is to weld a layer of wear-resisting, corrosion resistant, heat resistant properties of the metal layer of welding technologyon the surface of the workpiece or edge , . o repair and improve the service life of parts, the reasonable use of material, improve product performance and reduce the cost has remarkable economic benefits.
Overlaying welding work and working conditions are very complicated, it is overlaied according to the different requirements for selecting a suitable electrode. Different workpiece and surfacing electrode will use a different welding technology, to obtain satisfactory surfacing welding effect.
