Journal of Materials Research and Technology, 2020 Severe spattering is one of the common problems during fiber laser keyhole welding. In this study, the correlation between the spatter formation and laser-induced evaporation vapor on the front keyhole wall (FKW) was studied by changing the welding speed

Ytterbium fiber laser welding of Ti6Al4V alloy
Journal of Manufacturing Processes, 2015 Abstract In this work, full penetration welding of 2 mm thick Ti6Al4V plates in butt configuration was performed by adopting a high brightness Yb fiber laser. Neither groove preparation nor filler groove was used. The influence of different welding conditions on the bead morphology, metallurgy and mechanical properties was discussed in detail.
