Abstract

An explosive package is provided which is particularly adapted to be placed against and around the inside and outside curvature of a metal pipe for explosive welding purposes. The package is a substantially flat trapezoidal-shaped container, the shorter, non-parallel ends of which can be adjustably abutted against the non-parallel ends of a similar package in order to provide a continuous ring or band of explosives inside or outside the circumference of a pipe.
