An Ultrasonic Method for Testing Spot-Welds

TAKADA Hajime     HIROSE Tomoyuki

Abstract

The authors developed a technique for nondestructively evaluating spot-welds using Lamb waves throughtransmission technique. The nugget diameter can be evaluated by measuring the width of the zone where attenuated transmitted waves are observed. The authors also developed a measuring system using array transducers. The measurement results using the system agree well with the nugget diameters measured by cross-sectional observations.
