Technical Field

The invention relates to a method for manufacturing and remanufacturing a wear-resistant part by using a hard alloy stud

Background

The current method for manufacturing hard alloy studs and wear parts is insert casting. Fixing a certain amount of hard alloy studs on a casting mold of a wear-resistant part needing wear-resistant reinforcement, and after casting and solidification, or metallurgically combining or mechanically embedding the studs in a wear-resistant part matrix; the production efficiency of the hard alloy insert casting wear-resistant part is high, but the wear-resistant part with the hard alloy studs distributed in high density cannot be produced, because molten metal cannot flow into small gaps among the hard alloy studs to form effective insert casting connection to ensure the bonding strength.

The invention discloses a hard alloy stud for manufacturing a wear-resistant part by arc welding and a manufacturing method thereof, which are characterized in that a steel or cast iron or self-fluxing alloy spherical crown body which is welded on a wear-resistant part base body by an arc welding method and has a certain thickness and a certain diameter and is built up on the end surface is arranged at one end of an alloy cast stud, and the spherical crown body is a consumable electrode for arc welding and is welded on the wear-resistant part base body by the arc welding.
