Brazing Carbide Tool Tips With Induction

Brazing Carbide Tool Tips With Induction 

Objective: Attaching carbide cutters to a steel meat cutter impeller

Material carbide blocks; steel shank fitting

Temperature 1400 °F (760 °C)

Frequency 300 kHz

Equipment DW-UHF-30KW induction heating systems including: Induction heating coil Workhead: two-cap 1.0μF (Total 0.5 μF) Process The entire part is placed in a five-turn helical coil, the power is applied until the part is heated to the required temperature and a uniform heat pattern is achieved. The coil allows for easy fixturing and uniformity of heating between the carbide and the steel shank for a premium braze joint.

Results/Benefits

Precision: Due to the size of the induction coil, the process allows for precise placement of the carbides on the steel shanks

Economy: Power is consumed only during the heat cycle

Repeatability: joint quality is maintained in this repeatable process
