Abstract

In this paper we present results from process observations of deep
penetration laser welding using a hyperspectral imaging (HSI) technique.
For monitoring different types of laser-based material processing, we
developed an appropriate high-speed camera-based HSI system. This system
enables us to derive spectra of the deep penetration welding process
with high time resolution. These spectra can be used for temperature
determination or to extract spectral characteristics, both of which can
help to further investigate process dynamics and properties of the
vapor. The presented results contain particularly HSI-derived spectral
information of the evolving vapor plume that is related to corresponding
high-speed images and spectra acquired with a conventional
VIS-spectrometer.
