Effect of Filling Rate on Underwater Wet Welding Process and Weld Appearance. [PDF]
Materials (Basel), 2020 Real-time electric signal, matter transfer mode and welding pool behavior were obtained to investigate the effect of wires’ filling rate on arc stability and joints’ appearance during underwater wet flux-cored arc welding (FCAW). The electric signal results showed that arc stability first decreased and then increased rapidly because the raise of ...
