ABSTRACT:
Sealing and cracking problems occur when joining coarse-caliber pipes (1 and 2) for oil or gas, for instance, by means of welding. The problem is solved by using an outer peripheral part (3) and an inner peripheral part (4) at the joint, and applying the latter part (4) by means of explosive welding. At the same time, the outer peripheral part (3) forms a firm joint, due to the action of the explosive welding.
