摘要

Welding device comprises a welding head (4) which produces a peripheral welding seam on the connecting site of two workpiece segments (1,2). The head can be introduced into one of the segments to produce the welding seam. Preferred Features: The workpiece segment into which the welding head is introduced is a tubular projection which can be welded to the other segment to form a T-piece. The workpiece segments can be inserted into each other with interlocking regions. The welding device is an arc welding device.
