Explosive Welding Diagram

Explosive welding is used primarily for bonding sheets of corrosion resistant metal to heavier plates of base metal a cladding operation particularly when large area are involved.

Explosive welding diagram. This process does not include molten state during welding the different parts of metal which have to be welded. Explosion welding exw is a solid state solid phase process where welding is accomplished by accelerating one of the components at extremely high velocity through the use of chemical explosives this process is most commonly utilized to clad carbon steel plate with a thin layer of corrosion resistant material e g stainless steel nickel alloy titanium or zirconium. The principles of explosive welding have been schematically illustrated in fig. Dupont applied for the patent of this welding process in 1962 which was granted on june 23 1964.

Today we will learn about explosion welding principle working types application advantages and disadvantages with its diagram. Explosive welding diagram explosive welding working exw. Explosive welding is a specialised process used for lap joints in diffi cult to weld metals and their combinations. Aluminium can be welded to copper and stainless steel to brass.

Explosive welding under high velocity impact was probably first recognized by garl in 1944. In simple terms an explosive weld is achieved by impelling the cladding plate against the substrate plate material using. This article deals with the classification of welding methods depending on the state of the material during welding. Aluminium and copper can be welded to stainless steel aluminium to nickel alloys and stainless steel to nickel.

In explosive welding welded parts plates are metallurgically bonded as a result of oblique impact pressure exerted on them by a controlled detonation of an explosive. Explosion welding is also a solid state welding process in which the welding occurs without application of external heat. Welding is the process of joining two similar metals and it is applicable in most of the field like construction of bridges huge buildings railways roadways automotive and aircraft construction pipe lines tanks and vessels machinery parts. Explosive welding was first recognized as a.

Explosive welding ew is a solid state welding process i e. Explosive welding differs from other traditional joining processes as it does not depend on melting of two metals to be joined or on plastic deformation of the surfaces in contact as occurs with cold or hot pressure welding. Explosive welding exw is a solid state solid phase welding process that uses a controlled application of large pressure generated by the detonation of applied explosives. Introduction explosive welding is a solid state welding process which uses a controlled explosive detonation to force two metals together at high pressure.

Applications of explosive welding. Plastic or pressure welding. Video explains explosive welding process with diagram in detail. In this type of welding no additional filler material is used.
