ABSTRACT:
A welded joint between pipes and pressure bearing elements, such as tube plates, pressure tanks, accumulators, or the like. The pipes and elements have a lip-shaped extension in the joint region. The joint connection is effected in this joint region by a full through-weld which is substantially free of crevices. The joint connection of pipe-to-element lies within the region where the pipe penetrates the element. A free space remains below the element lip between the pipe and the element. The space which is located above the element lip, and which is defined or bordered by the element lip, the pipe, and a centering bushing or sleeve known per se, is filled up with welding material. The centering bushing serves only as a temporary aid during the welding operation and is removed, e.g. is bored out, after the welding operation has been completed.
