Abstract

A pressure welding method is provided and a pressure welding machine (1) is provided with a frame (10), two welding heads (13, 14), mobile along a feed axis (41), and two adjusting units (17, 18). The adjusting units (17, 18) include feed drives (23) for the welding heads (13, 14). The two adjusting units (17, 18) are mounted so as to be axially movable (41) on the frame (10) and are interlinked with an adjusting drive (25) by means of a common adjusting element (26) and supported in a closed system of forces while receiving the pressure welding forces, thereby relieving the frame (10). The common adjusting element (26) is configured as a continuous spindle (27) having two self-locking threads (28, 29) that run in opposite directions.
