This paper expounds the oxyacetylene flare overlaying welding technology of tungsten carbide rod made to be metal matrix carbide ceramal compound overlaying welding layers. It relates the thermal effect property of the oxyacetylene flare, the operations request of the overlaying, the technologic process and the quality dominate of the overlaying welding layers. To integrate the tungsten carbide rod overlaying welding technology process of oxyacetylene flare, the layers capability, the examination results of slurry wear and microstructure, the paper discusses the heat source property affect on the property of the layers and resist slurry wear property of the compound wearable overlaying welding layer.
