Abstract
This paper presents the preliminary, experimental results of laser-vibration treatment to increase the roughness of aluminium melts in compliance with EN AW-6060 (AlMgSi0.5). Using this method, metal objects are melted with a mobile laser beam while being vibrated. The effects of laser beam scanning velocity on the shapes of aluminium melts were studied at the set laser power and vibration frequency. The studied parameter was the mean roughness Ra. The value of Raparameter grew significantly. The studies were undertaken to employ this technology for the purpose of intensifying the exchange of heat in aluminium heating panels.
