Description

When ultrasonically inspecting austenitic stainless steel, the objectives can be viewed as a requirement to locate, size, and classify anomalies within the austenitic stainless steel material. Most ultrasonic inspections are carried out using “A-scope techniques.” These techniques work well when used by a diligent and experienced operator. With the advent of two major subsystems: (1) a high-speed data-acquisition and imaging system, and (2) an automatic remotely controlled robotic scanning system. The limitations and character of such inspection becomes more system dependent, which can be readily demonstrated. Today’s ultrasonic equipment can be used without an immersion tank and without manual assistance to reliably couple ultrasound to the part under inspection. The use of automatic scanners and associated techniques permits data to be acquired with highly repeatable results.
