Brazing of tungsten carbide cutting tools with high hardness and wear resistance, especially at high temperatures can still maintain its high hardness, has been widely used in manufacturing various metal cutting tools. Brazed tungsten carbide is firmly connected to one of the most successful method for steel substrates, but the tungsten carbide cutting tools welding technology is an important factor in causing weld cracking.
Brazed tungsten carbide cutting tools mainly for its simple and compact structure, good rigidity, greater flexibility in use, adaptability and other characteristics, are used in precision machining, FMS, and other various metal cutting machining. Brazed tungsten carbide cutting tools are mainly using high-frequency welding brazing equipment. Induction brazing by induction heating to provide heat, or working through the induction coil is energized rather than directly on the tungsten carbide cutting tools, electrical energy transfer by induction method to tungsten carbide cutting tools, and selectively heating the surface of the part to be welded to the brazing A method of soldering temperature. Equipment brazed tungsten carbide welding process used by high-frequency induction heating equipment, high frequency induction brazing machinery and water cooling system and control system.
