Technological particularities of laser manufacturing

Abstract

The paper presents some investigations about the influence of the Nd:YAG laser welding parameters on the penetration and metal evaporation of single and dual pass weld in the case of thin sections of stainless steel sample. The metal loss during welding process was measured in order to establish the optimal values of welding parameters. The geometric size of the welded zone was measured using an SEM microscope in order to establish the correlation between the penetration and with at different values of welding parameters.
