Abstract
A method of cladding an outer tube (1) with an inner tube (2), wherein the inner tube is made of a corrosion-resistant material, for instance. The inventive is characterized by placing a number of explosive charges (3) in mutually spaced arrangement in the inner tube (2), in contact with or essentially in contact with the inner surface of the inner tube; filling the inner tube with a pressure-transmitting medium (4), preferably water; and detonating all explosive charges (3) simultaneously, so as to obtain a local metallurgical bond (6) at the regions of the explosive charges and so as to cause the inner tube (2) to expand into abutment with the outer tube (1).
