Blast Welding

(explosive welding), a method of welding based on the use of the energy of an explosion. The part to be welded (the projectile) is located at an angle to the fixed part (the target). On the collison of the parts as a result of the explosion, a cumulative stream of metal is formed and spreads over the surface of the parts; this causes plastic deformation of both parts, and they are welded together. The explosive most frequently used in blast welding is ammonite; the weight of ammonite used equals the weight of the projectile. Blast welding is used to join parts of differing weights (from several grams to several tons) and of different kinds of metal, including stainless steels, nonferrous metals, and refractory alloys.
