Abstract
Method of and apparatus for two-wave explosive cutting in which the two-wave form for the shock wave produced by the detonation is achieved by varying the progress of the shock wave to the target in sections normal to the line of cut. This object is achieved, in one embodiment, by supporting a strip of explosive material (24) on a shock wave delay element (21) which spaces the mid-regions of the strip of explosive further from the target than the side edges of said strip. On detonation, the shock waves (25) produced by the side edges (22b, c) of the explosive (24) have less distance to travel through the element (22) than the mid-regions and thereby the classic two shock wave fronts (25a, 25b) situation is obtained in the target.
