A pressure welding device () and a pressure welding method are provided. The pressure welding device () includes a plastification unit (), a positioning and compressing unit (), a controller (), and an advance unit () for a workpiece () and for the process axis (). The advance unit () has an open- or closed-loop controllable hydraulic advance drive () that is formed as an open- or closed-loop controllable electro-hydraulic direct drive for the process axis ().

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