Abstract
Friction stir welding (FSW) is a novel solid-state joining process that uses the heat generated by friction between the rotating tool and the joined metals. The process is especially useful for materials that are difficult to weld with conventional techniques, such as Aluminum and Copper alloys. The paper presents the welding process and eddy current testing for FSW joint in 7075-T651 and 5083-H111 commercial aluminum alloys. While 5083 is suitable for both electric and resistance welding, alloy 7075, exhibits poor weldability, mainly due to the presence of copper. The workpieces were in the form of plates 6 mm thick, produced with tool rotated at 355 rpm. The microscopic analysis of cross sections had revealed microdefects in form of small longitudinal voids, along the weld length, located 1-2mm underneath the surface, and size in the range of minimum 0.1mm (length). Most of voids were observed on samples welded at high tool rotational speeds. In order to detect such defects without the necessity of cutting the samples, eddy current method was investigated. The paper shows the laboratory testing results with external probes and selection of optimum frequency. The minimum size of detection defects and their location underneath the surface are also discussed.
