Abstract:
A method for joining workpieces in which a pressing device (1) is placed with its at least two pressing jaws (21, 22) in an open position against the workpieces (23, 24), and the pressing jaws (21, 22) are then uninterruptedly moved with respect to one another by means of a jaw drive (7, 50), while the workpieces (23, 24) deform plastically, into a terminal pressed position in which application of power to the press jaws (21, 22) of the jaw drive (7, 50) is controlled by a power control device that generates a power profile for application of the power between a first power when the jaws are in the open position and a second power at the terminal pressed position so that application of power follows the power profile and causes the terminal pressed position to be achieved and the workpieces thereby joined.
