An advanced ultrasonic training course designed for Level II, Level III and NDE management and Supervisory personnel. This course is also ideal for individuals planning to take the API QUSE, API QUSE-PA, or other Performance Demonstration Examinations such as for EPRI.
This course will present ultrasonic examination methods for flaw detection and Time of Flight (TOF) sizing methods and 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, characterization, and flaw sizing. Detection and signal characterization techniques will cover the effects of echo dynamics, rise and fall time, and pulse duration for the identification of the ultrasonic signals.
Sizing applications will cover Time of Flight (TOF) and Delta Time of Flight methods for ID Creeping Waves, Tip Diffraction, Bi-Modal, and Focused Refracted Longitudinal and Refracted Shear Waves, including the use of Phased Array. These methods are very effective for sizing shallow, mid wall or deep flaws.
ID Creeping Wave Method uses the effects of head waves and mode conversion to characterize flaws for non-quantitative sizing.
Tip Diffraction Methods use diffracted signals generated by the crack tip to identify the depth of the flaw. This method is great for ID or OD connected cracks, very shallow cracks, and mid-wall cracks.
Bi-Modal Methods use the effects of a combination of shear and longitudinal waves pulse trains to size mid-wall ID connected flaws.
Refracted Longitudinal and Shear Wave Methods use focused L-Waves and Shear waves
Focused, Phased Array shear and longitudinal waves provide an improved view of the crack mechanism and a better process for determining crack height. Various sizing methods with method will be covered.
