Explosive welding was first recognised as a remote possibility in 1957 in the United States, when it was observed that meial sheets being explosively formed occasionally stuck to the metal dies. During the intervening decade, the process has been developed from remote possibility to a well understood process, which has found considerable application to plate cladding, particularly applicable to the cladding of very large areas which can only be done less effectively by roll cladding.
