Abstract

Spot weld quality in terms of soundness of joint and nugget penetrations have been evaluated by ultrasonic technique. Furthermore, the variations in ultrasonic attenuation
characteristics caused by grain boundary scattering have been utilized to assess grain coarsening at weld metal due to spot welding heat. The interpretations of ultrasonic signals are found to correspond with the results obtained from peel off and shear tensile test and are at par with the optical and TEM observations..
