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 ...

Formation of α’ titanium welds by friction stir welding
Journal of Physics: Conference Series, 2020 Abstract In the present study, investigation of the macrostructure of α’ titanium alloy weld produced by the friction stir welding has been carried out. The welding process modes were also selected. It is shown that in case of insufficient load on the tool, an open weld defect is formed.

Weld Formation in Microgravity.
ISIJ International, 1998 In order to investigate the effect of gravity on the formation of a weld, gas tungsten arc (GTA) welding was performed both in a microgravity environment and in a terrestrial environment. The microgravity environment was produced for 10 sec with less than 10-5 G by a drop-shaft type microgravity system at Japan Microgravity Center (JAMIC). The material
