Some new insight into laser beam welding and cutting processes by Dirk Petring (Fraunhofer ILT)

Dirk Petring's (Fraunhofer Institute for Laser Technology ILT) plenary paper at the 6th International Symposium on Visualization in Joining and Welding Science through Advanced Measurements and Simulation in Osaka, JP, Oct. 2022. "Seeing is Believing - Some New Insight into Laser Beam Welding and Cutting Processes". See also: https://www.calcut.de and https://www.researchgate.net/profile/... The visualization of the dynamics resulting from laser-material interaction during materials processing such as laser beam cutting and laser beam welding fascinates scientists since more than four decades. Especially, the induced melting and vaporization as well as the resulting melt and vapor flow have always been a key topic on the way to a better understanding of the transformation and transport phenomena that occur. High-speed videography provides process analyses with excellent spatial and temporal resolution.
