Welding machine and method for producing a butt-welded joint

Abstract

The invention relates to a method for producing a butt-welded joint between tube segments of a tube made of a weldable plastic material using a welding machine and to a welding machine (10), two tube segments each being held by a clamping apparatus (11) of a welding device (21) of the welding machine, welding contact surfaces of tube end cross sections of the tube segments being fused by means of a heating element (22) of the welding device and the welding contact surfaces subsequently being pressed against each other by a handling apparatus (18) of the welding device using a joining pressure to form a butt-welded seam connecting the tube segments to each other in a joining plane, the welding device being controlled by a control device of the welding machine, a data model of a tube system having at least one tube and a plurality of butt-welded joints being stored in the control device of the welding device, the data model comprising at least one object dataset representing the corresponding butt-welded joint and each having attributes, the control device detecting at least one weld parameter of the welding device as another attribute for the corresponding butt-welded joint and adding this weld parameter to the object dataset.
