Control Board, PSQ 6000

Used in countless applications, welding systems made by the European market leader Rexroth are the first choice of satisfied car manufacturers, tier one suppliers, and welding equipment manufacturers worldwide. Rexroth PSQ 6000 offers supreme quality in spot welding. The PSQ 6000 control board with the unique quality monitoring system will ensure maximum process reliability on the production line using intelligent current/voltage or ultrasonic pulse monitoring and control. The innovative technology also includes in-process monitoring of the weld. This process is supported by documentation, logging and statistical process control via the BOS 6000 user interface. For process assurance Rexroth offers the option of retrofitting the PSQ 6000 control board, which can be used for current/voltage and ultrasonic control. It is part of the PSQ 6000 quality assurance system, which controls, monitors and logs the welding process. Integrated ultrasonic control and testing: Integrated in the process, the ultrasonic measuring system monitors the quality of the spot welds during the actual welding process. Ultrasonic pulses are used to control the size of the molten weld nugget, and to calculate and display the spot diameter. Adaptive current/voltage control: for demanding material and metal combinations Rexroth offers adaptive current/voltage control with monitoring functions for pass/fail assessments. Combined current/voltage control and ultrasonic testing: this allows accurate inspection of the molten state of the spot welds and includes online display of the ultrasonic transmission variations concurrent with current, voltage and resistance characteristics in one diagram.
