An assembly for welding together two metal tubes, said assembly comprising: a. a parent metal tube; b. a flyer metal tube; c. means for supporting said metal tubes in concentric disposition with the outer surface of one of said tubes being disposed in parallel, spaced-apart relation with the inner surface of the other metal tube so that the distance separating said opposed surfaces equals at least approximately 0.001 inch; d. two matched layers of explosive which will, during simultaneous detonation thereof, produce a general balance of forces along the resulting detonating fronts in a direction normal to said layers of explosive and, following detonation of the layers of explosive, maintain a pressure differential between the released and expanding gases generated by the detonation of the two layers of explosive below a predetermined amount, 1. one of said layers of explosive being disposed about the outer surface of the outer metal tube and the other one of said layers of explosive being disposed about the inner surface of the inner metal tube, 2. the loading produced by the layer of explosive disposed about a surface of said flyer metal tube being sufficient, upon detonation thereof, to drive the flyer metal tube into collision with said parent metal tube and to cause bonding between said metal tubes, and 3. the loading produced by the layer of explosive disposed about a surface of said parent metal tube being sufficient, upon detonation thereof simultaneously with detonation of the other layer of explosive, to preclude movement of the parent metal tube relative to the flyer metal tube in a manner that would prevent welding together of said metal tubes; and e. means for simultaneously detonating said layers of explosive along a common, generally planar front whereby the detonation is propagated parallel to the longitudinal axis of said tubes.
