This paper reports the investigation of the effect of a plate dynamic loading scheme upon bimetal joint formation at explosion welding with simultaneous stamping. The investigation results of the effect of technological parameters and matrix material upon a radial deformation and quality of explosive pressed аrmco iron+steel 3 bimetal are shown. It is determined experimentally, that additional punching in modes common for explosion welding, without their intensification, allow achieving considerable deformations and manufacturing qualitative bimetal blanks with a high factor of a part form.
