Abstract:
A clamp system and method for measurement and control of welding a first substrate to a second substrate is provided. The system comprises a squeeze clamp having to a first end and a second end. The system further comprises a motor connected to the squeeze clamp such that the first and second ends are movable to clamp the first substrate to the second substrate. The system further comprises at least one of an electromagnetic flux sensor, a current sensor, a position sensor, and a gap sensor disposed on one of the first and second ends for determining a first measured variable between the first and second substrates. The system further comprises a controller to control the motor to clamp the first substrate to the second substrate based on the first measured variable. The controller is in communication with the electromagnetic flux sensor, the current sensor, and the gap sensor.
