Abstract

There is a persisting trend in automotive industry to increase safety of passengers while decreasing the cost and fuel consumption of the car. Usage of ultra and advanced high strength steels for manufacturing of car body parts is a way, how to achieve this goal. However, the manufacturing process of these parts requires presence of Al-Si coating on the surface of the steel. This coating is composed of multiple sublayers, which are cause of various issues affecting the stability of welding process and strength of adhesive bonds between those parts. This paper investigates the possibility of homogenization of Al-Si layer by laser treatment in order to improve strength of welded and adhesive joints.
