In this paper, an attempt was made to employ conventional shear waves to investigate the quality of thin-plate welds. A quantitative measure of the weld pool width was suggested, and the alignment as well as the symmetry of the pool about the weld line is indicated without micro-sectioning the weld. Also, the relative grain sizes around the weld's fusion zone could be indicated by their corresponding ultrasonic attenuation. Mathematical relationships of ultrasonic attenuation with welding current and heat input rate were established.
