AB  - Rising energy demands together with environmental concerns have spurred increased focus on renewable energetics, leading to the widespread installation of photovoltaic power plants worldwide. Due to the unique solar dispersion angle over the world, different racking systems are also the subject of keen interest in mechanical support equipment. Different constructions require welded joints of construction parts with massive strain while exposed to weather conditions. Therefore mechanical properties of the joints of these systems are also being studied. This research is focused on the mechanical properties (such as microstructure and microhardness) of aluminium laser welded joints under different welding parameters. The main aim of this paper is to find ideal parameters of laser welded aluminium profiles ensuring durable construction for PV panels.
