Essay On Explosive Welding

Explosive Welding-Rough Draft The development of explosive welding was first recognized by Garl in 1944. But it was not recognized in the United States until 1957 when it was observed by Philipchuck that metal sheets that were being explosively formed would occasionally stick to other metals. Over the decades the process has been developed fully with large applications in the manufacturing industry.
Explosive welding is a solid-phase process where welding is accomplished by accelerating one of the components which produces high velocity interactions of dissimilar metals by a controlled detonation. By doing this the resultant composite system is joined with a durable, metallurgical bond. This explosive process is commonly utilized to clad carbon steel plate with a thinner layer of corrosion resistant materials such as stainless steel, nickel, alloy, titanium, and zirconium. Geometries that are usually produced are plates, tubing, and tube sheets, these are simple geometries because they are very limited during this process. During this process an explosive has to be detonated on the surface of a metal which generates a high pressure pulse. The pulse propels the metal at an extremely high speed, if this piece of metal collides at any angle with another piece of metal, then welding will
These advantages are; explosive welding has the ability to produce a bond between the two metals that will not necessarily weld together by conventional means. The process of explosive welding does not melt either of the metals, instead it plasticizes the surfaces of the metals, which causes them to come into intimate contact to create a weld. The principle of this is similar to other non-fusion welding techniques, such as friction welding. Another advantage of explosive welding is that large areas are able to be bonded quickly and the weld itself is clean because of the surface material of both metals is expelled during this
