摘要： PCT No. PCT/SE93/00136 Sec. 371 Date Aug. 19, 1994 Sec. 102(e) Date Aug. 19, 1994 PCT Filed Feb. 19, 1993 PCT Pub. No. WO93/16836 PCT Pub. Date Sep. 2, 1993.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).

摘要： The cladding method comprises placing explosive charges (3) in contact with the inner surface of the inner tube. The inner tube is filled with a pressure transmitting medium e.g. water. All the explosive charges are detonated simultaneously to produce local metallurgical bonds (6) and to expand the inner tube into abutment with the outer tube. The charges are pref. sized to produce a metallurgical bond 1-8 cm2. The explosive charges may be applied in strings which extend axially or helically. The explosive charge(s) may be inside the tube to amplify the pressure wave and improve the effectiveness in expanding the inner tube. A gap (8) is defined between the inner and outer tubes before detonation. The gap is evacuated to 1 mbar before detonating the explosive charges. The explosive charges are placed in plastic, paper or rubber hose or onto a plastic or rubber sheet before insertion into the tube.

摘要： A charging system for seam welding two or more workpieces by means of explosion welding, comprising an explosive charge and an inert impulse-transmitting body located between the explosive charge and the workpiece nearest the charge. The invention is characterized in that the surface (11) of the inert body (2) facing the workpiece is so configured in a plane extending at right angles to the longitudinal extension of the ultimate weld seam that the angle alpha between the surface (11) and the workpiece (3) varies from the center line (C-C) of the inert body (2) perpendicularly to the surface of the workpiece and outwardly from the center line.
