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.
Claims21
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;
- and
- a controller communicatively coupled to the sensor, wherein the controller is configured to receive the acquired data from the sensor, and to output one or more control signals to control a laser parameter and a weld parameter of the laser hybrid welding operation based at least in part on the acquired data.
A laser hybrid welding system, comprising:
- a welder configured to perform a laser hybrid welding operation m 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;
- and
- a controller communicatively coupled to the sensor, wherein the controller is configured to receive the acquired data from the sensor, and to output one or more control signals to alternate between control of a laser parameter of the laser hybrid welding operation and control of a weld parameter of the laser hybrid welding operation based at least in part on the acquired data.
