Keyhole Instability Impact on Laser Welding Porosity by Sara Eid is a document available to read on EtoBox.
This study investigates the impact of keyhole instability on porosity during the deep penetration laser welding of 6061 Aluminum Alloy. A three-dimensional model simulates the molten pool and keyhole dynamics, revealing that abrupt changes in keyhole depth lead to bubble formation, which contributes to porosity defects. The findings emphasize the importance of keyhole stability in controlling weld quality and suggest methods for improving laser welding processes.
