Method and device for producing a butt-welded joint

A method for producing a butt-welded joint between two pipe segments (38, 39) of a pipe (27, 28) made of a weldable plastic material, each pipe segment being held by a gripping means (14, 15), pipe end cross-sections of the pipe segments (38, 39) being machined with the aid of a tool means (11) for forming welding contact surfaces (40, 41), said welding contact surfaces (40, 41) being melted by means of a heating means (12) and in the following being pressed against each other with a joining pressure for forming a butt weld which connects the pipe segments (38, 39) with each other in a joining plane (42),

• characterised in that
• said tool means (11) is disposed in a stationary manner in a separating plane (37) for machining the welding contact surfaces (40, 41) and in that a separating cut for forming the pipe segments (38, 39) is realised by the gripping means (14, 15) moving the pipe (27, 28) relative to the tool means (11) in the separating plane (37), said separating cut simultaneously serving to form the welding contact surfaces (40, 41).
