A unique thermoresistive method is used to study the parameters of the shock-compressed gas in the gap during explosive welding of copper and steel plates at a contact point velocity Vc = 2.6–2.9 km/s. At the shock wave front, the peak values of the heat flow power from the shock-compressed gas are found to be ≈1.5 and 0.5 GW/m2 for welding copper and steel, respectively, which is due to the lower deceleration of denser copper particles and their concentration at the shock wave front. Near the contact point (under the inclined part of the flyer plate), the heat flow power during welding of copper and steel plates is comparable (1 and 0.7 GW/m2, respectively), which is associated with a low concentration of metal particles in this region.
