    The use of an active-flux in TIG welding has proven to increase the weld penetration and to improve productivity significantly. This paper describes experiments to apply active-fluxes, like SiO2, Cr2O3 and NaF mixtures in laser welding. The experiments were carried out using both CO2 and Nd:YAG lasers. During laser welding there is no influence of an electric current on the welding plume like in the TIG process. Nevertheless, some characteristics of the plume were affected by the components of the fluxes. This was detected by a spectroscopic analysis and is discussed in this paper. As a result of the fluxes, a deeper penetration has been achieved. Moreover, the typical nail head shape of the weld disappeared when using fluxes in Nd:YAG laser welding resulting in a constant width of the weld.
