Evaluation of welding process stability and weld formation during laser-MIG hybrid welding
Journal of Physics: Conference Series, 2021 Abstract In laser-MIG hybrid welding, the visual information can be used to monitor the stability of the process and estimate the weld formation. Taking the hybrid welding of ER308 stainless steel as an example, a high-speed camera is used to simultaneously obtain visual information of top and bottom of the weldment during the welding ...
