Abstract:
This paper presents methods for the temperature calculation based on experimental data on the interface bond and in the heat-affected zone under conditions of impulse metal deformation during explosive welding. The methods are based on the formation of a thermocouple during the explosive welding of copper and constantan, with a hot junction on the boundary. An inverse computational solution is proposed to determine the temperature–time relationship at the interface from the measured potential distribution on one of the thermocouple reference junctions. The dependence of the joint (copper–constantan interface) temperature on time, defined by the maximum and residual temperatures, is determined. The temperature in the heat-affected zone spaced 0.3 mm apart from the weld is obtained. Major heat emission as well as metal melting occur in a narrow zone, significantly smaller than the zone of severe plastic deformation (wave formation zone). A mathematical model of the explosive welding temperature field is proposed, in good agreement with the experimental results. © 2022 Elsevier Ltd
