Abstract

In this article, the reactions and optimal parameters were investigated for molybdenum layers produced on aluminum substrate using single beam ytterbium fiber laser. To produce these layers the molybdenum powder (25–45 µm in size) was placed on the aluminum sheet substrate and successfully treated – along the entire length with 16 different irradiation modes. The microstructure of the prepared samples of welded joints was observed by using a light microscope (LM) and a scanning electron microscope (SEM). Reactions between molybdenum powder and aluminum substrate were examined by energy dispersive X-ray analysis (EDX). The evaluation of optimal parameters was determined from appearances of welded joints, namely their heights and depths.
