Abstract
Abstract New developments and characteristics of high brilliant laser sources have led to new applications in the field of laser remote processing. Due to high particle formation rates within the vapor plume, a significant influence of the interaction between laser radiation and nanoparticles on the process may occur. The presented work shows results of the investigation of the dynamical formation of nanoparticles within the vapor plume during the welding of stainless steel with a 2 kW Multi-Mode fiber laser under laser remote conditions. The particle size distribution is measured by the evaluation of TEM-images, whereas, the plasma temperature and particle density are analyzed in dependence of the irradiation time.
