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 ...

Advanced Engineering Materials, EarlyView.Thermomechanical fatigue tests of laser beam powder bed fusion (PBF‐LB) Inconel 718 show that the additively manufactured material reaches almost the lifetimes of conventionally‐rolled material under no‐dwell conditions. Introducing dwell times at the maximum temperature markedly reduces the lifetimes due to pronounced grain boundary sliding associated

Monitoring of aluminum alloy weld formation using TIG based on passive vision
Hanjie xuebaoDuring the butt-welding process of thin-plate aluminum alloys, the base metal was affected by fluctuations in the joint gap and uneven heating and heat dissipation. As a result, the weld was usually defective. A passive vision sensing method was selected
