The metal surfaces are ground and fixed parallel. Special formulated explosive powder is placed on the cladder surface. The detonation front travels uniformly across the cladder surface from the initiator and the cladding material collides with the backer at a specific velocity and impact angle. Oxides and impurities are expelled, leaving the plate surfaces metallurgical pure and creating a metallurgical weld between the two metals. After this process is performed, the newly formed clad is flattened, annealed if required as well as tested and inspected.
