Abstract
A significant influence of "channel processes* propagating at superdetonation velocity in the welding gap (cumulative jets, shock waves in gas, bending vibrations of plates and other) is manifested in explosion welding of long items. The paper presents the known data and results of authors' experiments which allowed clarifying the mechanism of pre-welding erosion of the surfaces of long steel parts being joined. The main element of this mechanism is heating and loss of the surface layer material at ricocheting collisions with the cumulative jet particles.
