An investigation of the effects of electromagnetic stirring and sonic vibration on weld microstructures, porosity, physical properties, and weld shape has been made using 5183 aluminum filler alloy (aluminum - 4 1/2% magnesium alloy). Grain refinement and elimination of the characteristic dendritic weld metal solidification pattern was the principal effect found. The results show no beneficial effect on properties, and no degassing tendency. The degree of grain refinement obtained with electromagnetic stirring and impact vibration was compared to that obtainable with heterogeneous inoculation. The latter method of grain refinement is the most effective although, again, no beneficial effect on properties was determined. A Viscous Shear Theory is offered to account for the grain refinement obtained with stirring and vibration. (Author).
The evolution of mechanical properties and its characterization is important to the weld quality whose further analysis requires mechanical property and microstructure correlation. Present book addresses the basic understanding of the Friction Stir Welding (FSW) process that includes effect of various process parameters on the quality of welded joints. It discusses about various problems related to the welding of dissimilar aluminium alloys including influence of FSW process parameters on the microstructure and mechanical properties of such alloys. As a case study, effect of important process parameters on joint quality of dissimilar aluminium alloys is included.
