Abstract: The invention relates to a welding accessory (1) to support and centre two pipe ends (2a, 2b) to be butt-welded. The welding accessory (1) comprises a central guide frame, (3, 4, 5a-d), over which the two pipes ends (2a, 2b) can be slid, provided with supports (13a-d, 16a-d) and with pressure means, for pressing the supports against the pipes walls. The supports (13a-d) have a triangular or trapezial shape and have a radius of curvature of the pipes. The space between the supports (13a-d) is filled by auxiliary supports (16a-d), also having a triangular or trapezial shape, which are pulled in place by springs (18a-d).
