Abstract
A metal sleeve having a substantially cylindrical outer surface and having first and second inner surfaces tapering outwardly longitudinally from at least adjacent the center thereof is formed to provide equal angles with abutting ends of two hollow cylindrical members such as pipe; the center inner surface of the sleeve is formed to contact abutting ends of the two hollow cylindrical members at least adjacent the ends thereof. The sleeve has a high explosive mass placed circumferentially thereon and is formed of a circumferential body having a greater thickness at least adjacent the center of the mass than at its ends such that on detonation maximum explosive impact is exerted inwardly toward said sleeve to weld the abutting ends together.
