SPATZ+ Servo Weld Guns & Actuators
An essential requirement for a good weld spot for both aluminium and steel spot welds is the reproducibility of the electrode force. This must always be guaranteed in all gun positions, even at interferences. Matuschek servo weld guns are equipped with a servo-electric actuator for building up the gun force (with integrated encoder and force sensor) and a likewise servo-electric actuator for optimal compensation of the gun weight in electrode direction (gun compensation).
The SPATZ+ technology control system evaluates motor current, encoder and force signals from the gun in real time and reliably compensates for disturbances through fast evaluation and feedback to the main motor within a few milliseconds.
An asymmetrical distribution of the welding force of the electrodes to the component caused by
a changed gun position and/or
by incorrect positioning of the components to be welded and/or
by asymmetrical cap grinding
is compensated down to a few Newton by the low-friction servo-electric gun compensation in combination with adaptive control. Welding guns equipped with these technologies enable reproducible and reliable spot welding of even the most demanding aluminium and steel sheet combinations.
Matuschek welding guns are available in C and X design in scalable sizes.
