Abstract
We present an innovative real-time monitoring technique based on the correlation analysis of the plasma plume optical spectra generated during laser welding of Al alloys. In particular we show that it is possible to determine the transition between the two main welding modes: keyhole and conduction. (C) 2007 Elsevier B.V. All rights reserved.File in questo prodotto:
