Abstract

Welding or joining of metals is probably as old as the invention of metals, when metals, were joined by heating and hammering (forge welding). Despite the early start, progress in the development of welding process was very slow; only in the 19th century, welding of metals was accepted as a potential technology for fabrication of metals, and since then the development work in this field started growing and presently it is considered to be a major fabrication process in the modern industries. With the introduction of more sophisticated and complex materials more and more novel techniques have been introduced for joining metals. Explosive welding is one of the latest techniques in the field of joining metals which can solve many joining problems.

Abstract

It has been reasonably well established that explosive welding is a form of pressure welding. To achieve a strong bond between the metal surfaces, it is essential to have the surfaces perfectly clean and the surfaces are brought together with sufficient pressure when inter-atomic repulsive and attractive forces will come into play resulting in bonding when equilibrium is reached.
