Abstract At the jointing of pipelines, especially underwater, as well as at the repair of damaged portions, a jointing piece must be inserted because the two pipe ends cannot entirely be jointed with precision. The invention proposes an explosive welding method with two explosive charges, by which method such a jointing piece can be welded-in rapidly and simply and the joint can be checked from the outside of the pipe.
