Description
Dissimilar joints between the aluminium alloys 2017A-T451 (Al, 4.14%Cu, 0.72%Mg, 0.68%Si, 0.6%Mn) and AlSi9Mg (Al, 8.6%Si, 0.31%Mg, 0.34%Mn) were fabricated by friction stir welding and computerised microtomography was employed to visualise defects. Welding was conducted at a rotational rate of 560 rpm and a tool speed of 560 mm/min. Microstructure was observed by optical microscopy, x-ray microtomography experiments were conducted using a laboratory scanner and image processing was undertaken by Drishti software. Issues discussed include the occurrence of shrinkage porosity and tunnel defects and the relationship between defect formation and welding tool parameters.
