Abstract
When joining together pipes the pipe ends are usually placed opposite each other and then welded together. This cannot be done with heavy pipes. A gap exists between the ends (3 and 4) to be joined. The invention provides a joint by producing a splicing tube (5) the length of the gap and joining this by means of explosive welding. The invention is also applicable for mending a defect (2) in a pipe (1) by the removal of a sufficiently large section of the pipe (1) to allow the splicing tube (5) to fit into the space obtained, the part removed containing the defect (2).
