EXPLOSION WELDING PROCESS- THE PROCESS OF SELECTION IN DISSIMILLAR METAL JOINING

Explosion welding is an effective technical engineering solution method in joining plates, of very different or similar metals, which are from technological and economical aspects not suitable for any other joining in the composite material.. The corrosion resistant materials like steel, aluminum and their alloys, titanium, zirconium, tantalum, frequently in process chemical, nuclear power, space and air force, shipbuilding, food processing and pharmaceutical industries at shells, engines, pressure vessels, pumps and heat exchangers production are used. Due to high cost of mentioned high quality properties materials, only solution for their extensive application is clad material (primarily by explosion welding) in the form of two-layer or multiple-layered material where corrosion resistance of an expensive metal is combined with strength and economy of another. Very different metals, such as copper, aluminum and their alloys, different steel grades, and metals with high melting point are joined with the explosive welding, too. They must fulfill the condition of minimal ductility and impact toughness. The explosives are the source of necessary and controlled amount of high density and action rate energy.
