Abstract

A keyhole enhances the absorption coefficient greatly and helps the laser energy to penetrate deeper into the material in laser welding on aluminum alloys. We set up a simple model to estimate the threshold conditions to form a keyhole and analyzed the effects of various parameters on laser welding theoretically and experimentally. By the measurement of the spectral signals the laser welding state can be monitored during processing.
