Explosive welding of metal plates

This paper describes a study of explosive welding of metal plates. The properties of a locally prepared mix of 77/23 ammonium nitrate and fuel oil (ANFO) explosive and the dynamics of the plates are investigated and the results from welding tests presented. The strength of the clad plates is measured and ultrasonic inspection performed to identify and locate defects. The welding process is simulated using a finite element-based computer model. A brief description of the modeling process is given along with the results from the simulations for comparison with measured parameters.
