Background The metal mold is made of metal materials, and is used in batch preparation of workpieces, cracks can be generated due to the action of various factors in the use of the metal mold, the depth of the cracks can be gradually increased when the cracks appear, and further the precision of the metal mold is possibly reduced due to the increase of the cracks, so that the metal mold cannot be used continuously. Electromagnetic thermal crack arrest techniques are based on current concentrating effects and thermo-mechanical coupling. When pulse current passes through a metal mold with cracks, the tips of the cracks generate instant high temperature due to high concentration of current density, so that the metal at the tips of the cracks is melted and forms local build-up welding, and then in the ultra-rapid cooling process, the areas at the tips of the cracks are subjected to impact quenching to form ultra-fine cryptocrystalline martensite, fine carbide and other strengthening tissues. However, in use, interference to metal equipment is caused by the action of external force in crack arrest repair of the metal mold, and then the deviation condition caused by unfixed metal mold occurs, so that the electrode electrically connected with the metal mold is dropped, and then a certain potential safety hazard exists in current generated at the electrode end, and after the current repair is completed, rapid cooling is required, insufficient cooling can cause poor impact quenching effect, and further the quality of the repaired crack is not up to standard.
