Abstract: A fast response weld head which employs a control system to allow user control of critical welding parameters such as speed, force, position, and duration. In one embodiment, the control system includes a position servo loop attached to a motor driven output shaft on which a welding electrode is mounted utilizing a follow-up spring assembly. During a weld cycle, the control system moves the welding electrode toward a workpiece at a rapid user-defined rate. Just prior to when the electrode is reduced to prevent damage to the parts. When contact is made, the force exerted by the electrode on the workpiece is measured until the measured force equals a user-defined optimum welding force. A user-defined weld current is enabled to the electrode. When the weld is complete, the welding electrode is automatically raised by the control system, releasing all pressure on the workpiece. In a second and presently preferred embodiment, a linear magnetic actuator is utilized in lieu of a motor to drive the output shaft.

Abstract: The motorized weld head employs a control system which allows user control of critical welding parameters such as speed, force, position, and duration. The control system includes a position servo loop attached to a motor-driven output shaft on which a welding electrode is mounted via a spring. During a weld cycle, the control system moves the welding electrode toward a workpiece at a rapid user-defined rate. Just prior to when the electrode contacts the workpiece, the speed of the electrode is reduced to prevent damage to the parts. When contact is made, a pressure transducer measures the force exerted by the electrode on the workpiece. A comparator continuously monitors the force measured by the transducer and changes state when the measured force equals a user-defined optimum welding force. A signal is then passed to the servo loop commanding it to hold the position of the electrode effectively maintaining the applied force on the workpiece.
