Patent ID: 10926359

Abstract:
A carbide saw blade and the welding method of the carbide saw blade includes: S1, heating the carbide tool bit, the saw blade base (the saw blade base's tooth seat part), the welding wire and the welding flux that well-placed; S2, at temperature 760° C.-840° C., spreading the melted welding wire to the gap between the carbide tool bit and the saw blade base by using the wetting action of the welding flux; S3, cooling to obtain a preliminary welding body, when the temperature of the preliminary welding body is lower than 350° C., the preliminary welding body will be processed to first tempering; S4, within 1-3 hours after first tempering, second tempering the preliminary welding body to obtain carbide saw blade; second tempering process is performed in a sealed container, and in this container the temperature of each spatial location is consistent.
