Motorized Servo Weld Heads

The application and control of force during the resistance welding process is extremely important. The mechanical system to do this is generally referred to as the weld head. The weld head (including the welding electrodes), functions to force the workpieces together and hold them during the weld. The weld head provides the current path, welding pressure or force, triggers (initiates) the weld current, provides follow-up force as the workpieces melt together, and cools the workpieces after the weld.

Motorized servo weld heads are actuated by a servo motor and are programmed by an external control box.

• Adjustable approach points for ease of part positioning
• Speed between these points is independently adjustable
• Impact is determined by motor speed
• Follow up force can be set via a control box
• Can have a spring loaded force module for fast follow up
