Abstract
A method for extruding synthetic welding material using a welding device for synthetic welding material for the purpose of producing welding seams is characterized by the following features: a) A plastic wire is drawn by a feed device into the welding device (11, 12, 38) for synthetic welding material; b) The plastic wire is fed by the feed device (11, 12, 38) with a specific advancement into a cutting device (26, 36) of the welding device for synthetic welding material; c) In the cutting device (26, 36), pieces are cut consecutively from the plastic wire while forming essentially even cutting surfaces; d) The advancement of the plastic wire and the cutting frequency of the cutting device (26, 36) are in such a ratio to each other that the cut-off length of the pieces is in the same magnitude as the mean diameter of the plastic wire; e) The pieces are then heated until they are plastified; f) The plastified synthetic material is ejected as synthetic welding material from the welding device for synthetic welding material.
