F063: How to be Successful in Laser Joining

This presentation offers an in-depth examination of essential factors that drive successful laser welding operations. Critical parameters such as wavelength, beam quality, spot size, and sophisticated beam shaping methods will be explored to demonstrate their influence on weld performance and productivity. Attendees will gain insight into core welding methodologies, including keyhole, conduction, and hybrid approaches, along with their distinct benefits. The session will also address the selection of appropriate joint configurations for various materials and applications. Common laser welding obstacles—including cracking, porosity, spatter formation, and challenges with reflective materials—will be tackled through detailed case studies showcasing effective optimization solutions. The presentation will conclude with an emphasis on robust process control, highlighting critical factors such as power settings, welding speed, spot size, beam manipulation, vision-based weld positioning systems, and real-time monitoring techniques to ensure superior weld quality and repeatability.
