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 ...

Effect of kerf characteristics on microstructures and properties of laser cutting–welding of AA2219 aluminum alloy

Journal of Materials Research and Technology, 2021
The purification of laser keyhole is an important means to remove the oxide layer of laser-MIG hybrid welding of aluminum alloy. Four common auxiliary gases (argon, nitrogen, air and oxygen) were used to prepare kerf with different characteristics, which

Comparison of joining efficiency and residual stresses in laser and laser hybrid welding [PDF]

, 2011
Laser welding is a high energy density process, which can produce welds with less energy input and thereby lower residual stress generation compared to arc welding processes.

Effects of Laser Offset and Hybrid Welding on Microstructure and IMC in Fe–Al Dissimilar Welding

Metals, 2017
Welding between Fe and Al alloys is difficult because of a significant difference in thermal properties and poor mutual solid-state solubility. This affects the weld microstructure and causes the formation of brittle intermetallic compounds (IMCs).
