21. A method for pressure welding, of workpieces by means of a controlled pressure welding device, the method comprising the steps of:
-
plasticizing the workpieces by means of a plasticizing unit; and positioning the workpieces relative to one another and compressing the workpieces along a process axis by means of a positioning and compressing unit; moving a workpiece along the process axis by means of a feed unit with a controlled or regulated hydraulic feed drive, wherein the feed is effected with the feed drive, which comprises a controlled or regulated electrohydraulic direct drive for the process axis. - View Dependent Claims (22, 23, 24, 25, 26, 27, 28, 29)
