Some applications of interlayer explosive welding

ABSTRACT

Interlayer plays an important role in improving the welding quality of explosive welding. In this study, four different welding interfaces were subjected interlayer explosive welding to demonstrate advantages of interlayer explosive welding over direct welding. The results indicated that using an interlayer in explosive welding could reduce excessive melting, enlarge the weldability window, reduce the vortex region, and reduce the large plastic deformation between interfaces. Smoothed particle hydrodynamics (SPH) simulations were used to simulate the different welding processes, which provided information on the interface morphology, temperature, melting, and pressure. The simulated results were found to correlated very well with the experimental results.
