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.

Effect of Laser Deoxidation on Adhesive‐Bonded Aluminum in an Oxygen‐Free Atmosphere

Advanced Engineering Materials, EarlyView.
This study investigates laser ablation of aluminum under oxygen‐free conditions. The goal is to produce oxide‐free substrates that enable improved adhesive bonding with epoxy. Optimized laser parameters (90% overlap, 300 µJ) combined with oxide‐free substrates result in the highest tensile strength of the adhesive bond.
