Results were presented last year to demonstrate the feasibility of using an ultrasonic phased array to inspect spot welds. Analysis of the signals in the Fourier domain allows identification of satisfactory, undersized and defective welds. Signal- and image-processing techniques have been implemented with the goal of extracting the dimensions of the weld nugget. The results presented here were obtained using a portable phased-array controller. Toward developing a fully portable system, a housing for the probe is under development with an integrated mechanical scanning system.
