Abstract
Abstract A cladding article with a charge of detonating explosive is located on the cladded article with a pre-determined spacing between them. The value of this spacing is maintained on the entire welding surface by means of metal elements which are physically separated from the welding articles. Each metal element is provided with a cavity open at the ends, with the ends of the walls confining the cavity facing the welding surfaces of the articles. The thickness of the wall should be, at least, by one order smaller than the thickness of the cladding article. The metal elements are located so that a sufficient number of them with their ends contact simultaneously the welding surfaces to hold reliably the cladding article with a charge of detonating explosive on the cladded article. The cladding is accomplished by explosive welding.

Claim 1
Independent Claim
196 words
In a method of cladding metal articles by explosive welding, including positioning a cladding article carrying a charge of detonating explosive in spaced relationship with a metal article forming a base member which is to be cladded therewith so as to provide a uniform spacing between their mutually facing welding surfaces, the improvement comprising: locating a plurality of upright, thin-walled hollow scattered elements at intervals over the entire welding surface between said cladding article and said base member; each said metal elements having a cavity open at opposite ends facing the respective welding surfaces of said base member and cladding article, the thickness of the wAlls of said hollow member being substantially constant along the height thereof and of at least one order smaller than the thickness of said cladding article; said metal elements being arranged so that a predetermined number of their ends surfaces concurrently form direct contacts with the welding surfaces of said cladding article and said base member so as to maintain said cladding article, together with the charge of detonating explosive, in contact with the welding surface of said base member, and maintain said spacing prior to the instant of explosive welding.
