This invention pertains to a method and apparatus of non-destructive testing wherein a generally bidirectional wave generating electromagnetic acoustic transducer is pivotally mounted upon a base with this transducer being continuously rotated or oscillated upon the base as it is moved with respect to the workpiece (or the workpiece is moved with respect to the base). This oscillation or rotation causes a wave to be generated along an arc with these waves extending radially outward from the base so that any flaws in the workpiece can be struck at an angle as close to 90 degrees as possible (the optimal incident angle).
