WELDING METHOD OF WEAR RESISTANT OVERLAYING LAYER AND WEAR RESISTANT MATERIAL FOR USE THEREIN

摘要

The present application aims to produce the highest level wear resistant material by a general welding method, and the configuration is weld-coated on a ferrous base material M using a MIG welder. The component of the wire 30 used for welding turns into the matrix of the coating layer L. FIG. A fixed amount of cemented carbide particles G is added to the melt pool P during welding. The particle size of the three-dimensional (G) is 0.5 to 3.0mm, and evenly dispersed in the matrix at a ratio of 30 to 70% by weight relative to the entire coating layer, using a widely used MIG welding machine, the material of the matrix Since it is selected from a wide range of metals, the wear resistant material that is most suitable for wear conditions can be easily manufactured.
