The relationship between the weld strength, crystallographic texture, and grain size in Al-Al ultrasonic welding was investigated in order to develop a parameter optimization method. The weld strength and cross-sectional microstructure of the welded interface were measured on samples of two aluminum plates which had been welded ultrasonically using various amplitudes and times. For the low strength and interface fracture, the crystallographic texture was simple shear texture components, and the grain size was finer than before welding. On the other hand, for the high strength and upper plate fracture, the crystallographic texture was the same as above, but the grain size was coarser than before welding. The relationship between the strength and the microstructure was hardly affected by the combination of amplitude and time. These results suggest that the welding parameters can be optimized using crystallographic texture and grain size.
