Overview of Nondestructive Testing (NDT) Inspectioneering

Nondestructive Testing (NDT) consists of a variety of non-invasive inspection techniques used to evaluate material properties,components,or entire process units.The techniques can also be utilized to detect,characterize,or measure the presence of damage mechanisms (e.g.corrosion or cracks).NDT is also commonly referred to as nondestructive examination (NDE),nondestructive evaluation OmniScan MX2 Phased Array Flaw DetectorThe OmniScan MX2 phased array flaw detector with touch screen interface offers increased testing efficiencies and powerful software features,ensuring superior manual and advanced AUT application performance with fast setups,test cycles,and reporting.It isNondestructive Testing StandardsDetected flaws are evaluated for possible rejection due to nonconformance to set acceptance criteria.These nondestructive testing standards are instrumental to laboratories and a wide variety of industrial plants for examining a material's quality and,consequently,suitability for intended use.

Introduction to Ultrasonic Testing

Ultrasonic Testing (UT) uses high frequency sound energy to conduct examinations and make measurements.Ultrasonic inspection can be used for flaw detection/evaluation,dimensional measurements,material characterization,and more.To illustrate the general inspection principle,a typical pulse/echo inspection configuration as illustrated below Inspection/Non Destructive TestingThis latter document sets defect Acceptance Criteria for the NDT applied at manufacture.The acceptance criteria take into account the capabilities and limitations of the NDT techniques so for Radiography it states No cracks allowed whilst for Ultrasonics it states conditions on planar indications based on the height,length and amplitude.Inspection Methods Overview and Comparisoning,and ultrasonic testing.This chapter provides an overview of the in-spection methods that will be covered in the remainder of this book.Visual Inspection.Visual inspection provides a means of detecting and examining a vari-ety of surface flaws,such as corrosion,contamination,surface finish,and
