Effect of the filler metals on aluminium alloy joints

TL;DRAbstract

One of the most favored welding techniques of high strength aluminium alloy is commonly metal arc welding (MAW) process due to its high productivity and relatively low production cost. Apart from other process parameters (e.g. joint design) the filler material has a significant influence on the microstructure of the weld at the joint and consequently on the endurance limit of the end-product. The above considered process was used to weld AA6082 aluminum alloy using two different filler metals, Al4043 and Al5356 respectively. In this paper morphological, compositional analysis and mechanical characterization of the welded joints will be reported. Firstly, typical transverse sections of the weld joints samples have been observed using optical and scanning electron microscopy. The chemical composition at the interface has been monitored by energy dispersive X-ray spectroscopy. Secondly, orthogonal to the welding direction tensile tests have been performed aiming to provide both qualitativ
