Weld defect detection systems and methods for laser hybrid welding

摘要

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.

主权项

1. A laser hybrid welding system, comprising:
a welder configured to perform a laser hybrid welding operation in which a workpiece is heated by a laser and filler metal is added by an arc welding process; a sensor configured to acquire data regarding a parameter of the laser hybrid welding operation; an operator interface configured to receive inputs from an operator regarding the welding operation and to convey information to the operator regarding a status of the welding operation; and a controller communicatively coupled to the sensor and configured to receive the acquired data from the sensor, to determine whether the acquired data is indicative of a welding defect, and if the acquired data is indicative of a welding defect, to notify the operator that an error has occurred via the operator interface.
