Automated Welding Process Sensing and Control
Sensors which detect physical properties of the weld such as reinforcement area or fracture toughness, or which detect parameters that can be related to those properties such as depth of penetration or cooling rate.
A model of the welding process which relates the controllable welding parameters such as current, voltage, welding speed, etc., to the physical properties of the weld.
A control system which takes the signals from the sensors and converts them into a form which can be used for feedback control of the weld machine.
