Abstract
The inserting metal welding method is used to joint tungsten steel parts or to joint tungsten steel part with other metal part. The welded head has an expanded part, and the welded handle has one slot suitable for the un-expanded part of the welded head to insert in. The ring contact surface between the welded head and the welded handle is painted with welding paste and the welding paste is melted at 425-875 deg.c with one high-frequency heating equiopment during the welded head is inserted into the welded handle. So, the welded head and the welded handle are welded together. The said method has high welding concentricity and high strength and may be used widely in producing drilling bit, cutting tool, etc.
