Courses fundamental of welding science and technology. All the important events take place in the vicinity of point a, which runs behind the detonation front see fig. Introduction explosive welding is a solid state metal joining. A weld joint is produced by means of a high velocity impact of one metallic mass onto another, aided by a controlled detonation with an explosive charge. Explosion welding is also a solid state welding process in which the welding occurs without application of external heat. Introduction to pressure welding processes solid state bonding, friction welding, friction stir welding, ultrasonic welding, explosive welding, di. Which one of the following is not a solidstate welding process. Inpractice,regularuseismadeof aggressivereagents,towhichnormal. At tnopml several of the explosive welding configurations that were. Today we will learn about explosion welding principle, working, types, application, advantages and disadvantages with its diagram. In friction stir welding the interface to welded, the faying interfaces they dont really move instead we have a tool which actually plunge into the interface and then. Fusion welding in fusion welding or non pressure welding, the material at the joint is heated to molten state and allowed to solidify. Welding processes professor murugaiyan amirthalingam.
In plastic welding or pressure welding, the pieces of metal to be joined are heated to plastic state and then forced together by external pressure. In the process of explosive welding, the impact of two plates is accompanied, as a rule, by a stationary periodic process leading to a characteristic modulating waved interface see fig. Explosive welding is a solid state metal joining process used to create a metallurgical bond between two similar or dissimilar metals 1. Explosive welding an overview sciencedirect topics. Welding explosiveweldingofmetalsin avacuumenvironment. The bonding mechanism interfacial morphology is unique characteristics of which solidstate welding process. Two metal plates are join together by explosive welding process.
