Description

Rapid advances in automated welding and increased demands for reliable weld-quality inspection tools have created a need for new ultrasonic inspection systems. In particular, new systems capable of operation at elevated temperatures and rapid scan rates are in demand in fully and semi-automated welding applications to complement radiographic and conventional ultrasonic inspection techniques. In such applications, radiography is fundamentally limited because of its inability to detect and dimension most sharp flaws, and possible health hazards. On the other hand, conventional ultrasonic techniques are limited because they tend to be difficult to automate, require fluid couplants, and are often operator-dependent.
