Weld defect detection systems and methods for laser hybrid welding
Abstract:
Laser hybrid welding systems adapted to identify and/or fix a weld defect occurring during a laser hybrid welding process are provided. Embodiments of the laser hybrid welding system may include one or more devices that provide feedback to a controller regarding one or more weld parameters. One embodiment of the laser hybrid welding system includes sensors that are adapted to measure the weld voltage and/or amperage during the welding process and transmit the acquired data to the controller for processing. Another embodiment of the laser hybrid welding system includes a lead camera and a lag camera that film an area directly in front of the weld location and directly behind the weld location.
