Ultrasonic Immersion Testing System WELLS Krautkramer has introduced a new range of British designed and built ultrasonic immersion testing systems for detecting minute flaws in large, safety- critical components such as aero engine turbine discs and rings. Aircraft engines incorporate a number of large discs into the periphery of The three main axes, X, Y, and Z, are which turbine blades are located. mounted on precision linear bearings High rotational speed of these com running on precision ground rails.
