Melt Pool and Keyhole Behavior Analysis for Deep Penetration Laser Welding [PDF]

open access: yes, 2010
One usually defines the main characteristic of the welding performances of a given laser system by its “penetration curve” that corresponds to the welding depth as a function of the welding speed Vw for a given set of operating parameters.
