Investigation of the Influence of Dynamic Parameters on the Formation, Structure and Properties of Bimetallic Compounds during Explosion Welding with Simultaneous Stamping

Abstract

This article reports on the study of the influence of dynamic parameters on the formation, structure and properties of bimetallic compounds during explosion welding with simultaneous stamping. The results of the study of the impact of the collision speed and contact speed on the strength, wave parameters and the amount of molten metal obtained by the explosion of a bimetallic compound of the iron + steel 3 alloy are presented. It is shown that the formation of a bimetal during explosion welding is significantly influenced by impact velocity, with an increase in which there is an increase in the values of the maximum deflection and radial deformation.

Kinetics of the Formation of Bimetallic Compounds and the Distribution of Energy Components in the Explosion Welding Process

“…In previous studies, it was shown [10,14] that the kinetic energy of the motion of the welded package can be effectively used for simultaneous stamping, combining this operation with explosion welding. Fig.…”

“…The role of this additional energy is great, since it can be rationally used for simultaneous forming (stamping) of a bimetallic billet. This will eliminate the use of expensive pressing equipment and increase the efficiency of the explosion welding process [12][13][14][15][16][17][18]. To obtain high-quality bimetallic compounds with a given part profile, it is necessary to know the real speed of the package movement and the actual total energy balance of the explosion welding process.…”
