Experimental-Calculation Estimation of the Temperature Field Distribution during the Hardening of Thin-Walled Parts by Electric Pulse Facing

The formation of temperature fields and tempering zones during electric pulse hardening of thin-walled parts is studied. A mechanism is developed to supply a filler wire for semiautomatic vibrational arc facing. The influence of the pulsed arcing parameters on the surface hardness of the part to be hardened is experimentally studied.
