What is an explosion welding?

EXW is a process of working with metal, which is sometimes also called explosive binding or explosive cladding. EXW considers the process in a fixed state and allows you to force two different types of metals along with a clean vacuum tight weld. This is done without heating one type of metal to the melting point or threatening the original properties of both. This is achieved when the speed of controlled detonations is used to create an atomic link that is often impossible if other welding processes have been used. Historically, this process has not been used most often, but is often considered a specialty.

EXW is a welding process that was introduced in the second half of the 20th century. It is assumed that the idea of ​​welding explosion is inspired by events in the First World War I. It is assumed that the process arose from observation about the way Shrapnel managed to weld on the armor of the soldiers.

explosion welding is considered to be a fixed status as two different metals can be connected without evenIt was achieved by its melting point. One of the main advantages of EXW is that it can be used to weld almost any pair of metals and most alloys. This option is significant because many pairs of metals or alloys are considered incompatible if they try welding using other processes.

The

weld from the EXW process is achieved by means of an energy generated from controlled explosions. The force of these explosions causes the outer layers of each metal surface to have a plasma form that allows coalescence. Although no item reaches its melting point, the surfaces may seem molten and commonly generated a certain amount of heat. Heat is partially produced due to the impact of a collision of two surfaces.

There are several remarkable advantages for explosion welding. First, metals will not lose its original features. Secondly, the joint that is the result of this explosive process tends to be exceptionally clean andVacuum solid. Thirdly, the process is done very quickly and can be used on large surfaces.

In decades after its introduction, welding explosions were generally considered a specialized process. The use of this method is considered to be minimal compared to its potential. This can be partially attributed to the fact that this process requires an extensive knowledge of explosives that many metal workers do not have.
