Abstract : In the continued evaluation of the in-process ultrasonic approach to the nondestructive inspection of resistance spot welds, ultrasonic through-transmission measurements were extended to several types of metals to establish signal sensitivity and behavior with respect to metallurgical changes. In addition, the test results are reviewed from the standpoint of meaningful trends and reproducibility required for the development of go-no go or absolute measurement type quality control devices.
