It just doesn’t get any better than this… This beautiful ultrasonic inspection head provides a convenient way to detect sub-surface defects in a machine tool and is a cost-effective alternative that provides an added measure of quality assurance without incurring the full costs of post-build inspection techniques such as micro computerised tomography (CT). Furthermore, since it can be undertaken in the same setup as material deposition, it warns of defects while there is still an opportunity to rework the affected area.
