Abstract
When joining together pipe-lines, in particular, by means of explosive welding, an outer support tool is generally used, together with an inner peripheral body (3) which is applied by means of explosives (5), to the inner surfaces of the pipes (1 and 2) to be joined. The object of the invention is to replace the support tool by a tube formed from a strip (10), said tube functioning as support during the explosive welding process and which can be removed if desired, by unwinding.
