Crack arrest in metal component with double spatial cracks using electromagnetic heating

The temperature field around a crack tip is simulated for the case when crack arrest is proceeding in a test piece with prepared spatial cracks using pulse current discharge, the thermal-electrical coupling analysis method is applied numerically, and the results are verified experimentally. The numerical simulation and experiment results show that the deposit joint can be formed around the crack tip, and the radius of curvature around the crack tip increases remarkably instantly after pulse current discharged.
