Abstract: New computational and experimental methods for studying the thermal processes occurring during metal explosive welding are developed based on the use of natural and local thermocouples and allowing one to reliably construct temperature fields in the heat-affected zone and thermal welding cycles. The basic regularities of thermal processes in the heat-affected zone during explosive welding are revealed. It is theoretically shown and experimentally confirmed that, in this zone, the heat released during detonation of the explosive can significantly increase the temperature of the contacting metal layers and lead to melting of the latter.

Keywords: explosive welding, thermal processes, heat-affected zone, natural thermocouple.
