Because the composite material of high manganese and alloy steel has strong toughness, the wear resistant alloy with very strong hardness can be surfacing welded on the surface, so that the surface strength of bucket teeth can be greatly improved, and the ideal bucket teeth can be obtained. Because of the strong principle in the process of drought resistance treatment, surfacing alloys with high hardness and good wear resistance should be selected in materials. If the strength of rock is not high, austenitic manganese steel surfacing alloy can be selected. According to relevant research, high bait cast iron alloy has stronger wear resistance than high manganese steel material. When manufacturing new bucket teeth and repairing old bucket teeth, high bait iron alloy or martensitic cast iron alloy are used. In the process of repairing, the old bucket teeth can be trimmed with acetylene flame, a certain groove can be left, and then the original shape can be treated with austenitic steel manganese electrode. Finally, surfacing treatment is carried out on the surface to improve the wear resistance of large mining excavators.
