Abstract

Abstract

Tool steel and copper were welded together using underwater explosive welding technique, which is preferably adopted for the welding of super-thin and super-hard brittle materials. In this work we carried out experimental research using inclined welding setup for high velocity explosive. Underwater explosive welding process was numerically simulated using ANSYS/LS-DYNA, the simulated results from which show that the colliding velocity decreases in the welding direction. The micro-characterization indicates that wavy is the dominant interface structure and the wavy structure decreases in the welding direction, according with the simulation. In addition, the micro-hardness test of tool steel welded with copper reveals a slight increase of hardness close to the interface.
