Feasibility Analysis on Powdery Emulsion Explosive in Explosive Welding of Aluminum-Steel and Titanium-Steel

The explosive welding of aluminum steel and titanium steel is carried out by using powdery emulsion explosive. The normal and high temperature shearing, normal and high temperature bonding, and lateral bending of the aluminum-steel and titanium-steel are investigated, and the interface morphologies including wave height, wavelength, and size of unwrapped compound at interface are analyzed. The application feasibility of powdery emulsion explosive in the explosive welding of aluminum-steel and titanium-steel is verified.
