Comparison of the microstructural and mechanical characteristics between gas tungsten arc welded and friction stir welded aa6061 aluminum alloy joints


AS Mohamed, SS Mohamed, AM Gaafer

This work involves a comparison between mechanical properties of AA6061-O welded joints using two different welding processes, typically, gas tungsten arc welding (GTAW) and friction stir welding (FSW). GTAW process was performed on Al AA6061-O plates of 6 mm thickness using ER4030 filler metal according to AWS with tungsten electrode (EWth-2) and various arc voltages and welding currents under argon shielding gas. Friction stir (FS) welded joints were produced using several tool rotational and welding speeds. All welded joints were subjected to X-ray radiography tests and defective joints are excluded. Several mechanical tests, typically, microhardness, tensile and impact tests were carried out to evaluate the mechanical performance of the welded joints. The results revealed that AA6061-O FS welded joints exhibit higher mechanical properties than those obtained by GTAW.
