With the PS 6000 system, ultrasonic measuring technology enables non-destructive quality test during actual welding process. For demanding material and metal combinations, Rexroth offers adaptive current/voltage control including monitoring functions for fully documented quality control. The current/voltage control displays all the process-critical parameters online in a diagram, enabling accurate inspection of the weld spots. The PS 6000 system solution features flexible scalability in terms of power and functionality. A modern Windows user interface, BOS 6000, offers fully-featured programming, monitoring and logging.
