Advanced UT Detection

An advanced ultrasonic training course designed for Level II, Level III and NDE management and Supervisor personnel. This course will present ultrasonic examination methods for flaw detection and Time of Flight (TOF) characterization techniques in materials susceptible to Intergranular Stress Corrosion Cracking (IGSCC/SCC), mechanical fatigue and thermal fatigue. These methods can be applied to piping, plate, and vessel components in petroleum, chemical, fossil, nuclear, and aerospace industries or any industry involved in ultrasonic examination of metallic product forms.

This "hands-on" practical advanced ultrasonic course includes shear wave and refracted longitudinal wave techniques for detection and signal characterization techniques to address the effects of echo dynamics, rise and fall time, and pulse duration for the identification of the ultrasonic signals.

• Ultrasonic Signal Characterization
