A computer code has been written to calculate realistic ultrasonic fields in solids. The program calculates the field due to a transducer coupled to the solid through either a fluid medium such as water or a solid medium such as a plastic shoe with a

The use of pulsed lasers for noncontacting generation of ultrasound in solid materials is expanding rapidly [1], as is optical detection of ultrasound [2]. The noncontacting nature of laser ultrasonics is opening new areas of research where physical

The feasibility of using automated ultrasonic examination with computer-based pattern-recognition techniques to inspect partially completed welds on a pass-by-pass basis is investigated. In these tests welds are inspected, as they are being made, by

A welding machine requires three additional basic components for truly automated operation: Sensors which detect physical properties of the weld such as reinforcement area or fracture toughness, or which detect parameters that can be related to those
