ULTRASONIC METHOD FOR MEASURING CRACK DEPTH IN STRUCTURAL WELDMENTS

Non-destructive methods capable of ascertaining the integrity of structural materials during fabrication and in service are very much in need. This paper deals with an ultrasonic technique developed for the purpose of determining the depth of cracks in structural materials. The technique has been applied on high strength steel plate weldments to study fatigue. The accuracy of the method was evaluated by comparing the depth of cracks obtained ultrasonically with the measurements after breaking the plate. Results show that depth increments of 0.1 in. are detected.
