Simulation of Temperature Field Induced in Localized Ultra-High Frequency Induction Brazing of Diamond Tools

Localized ultra-high frequency induction brazing is proposed to deal with the thermal deformation problem of brazed diamond tools. In order to investigate the temperature field distribution, the simulation model of induction brazing for solving the temperature field is described through the FLUX 2D software. The experiment is carried out to verify the numerical simulation result. Good agreement is observed between experimental value and simulation result. The influence factors on temperature field are investigated by the simulation software. Ultra-high frequency induction brazing with diamond grits is carried out based on the conditions given by simulation results. Good bonding between the diamond grits and the filler alloy is observed and the width of the brazed region is less than 3 mm.
