Concepts of Welding Defects and Discontinuities
Welding defects can be classified as structural discontinuities and consist of: porosity, slag inclusions, lack of fusion, cracks, etc. Porosity is gas pockets or voids in the weld metal which are free of any solid materials, such as It is formed as a result…

NDT – Few Other Methods
Here are some rarely used NDT – Few Other Methods 1. Eddy Current Testing – ET: Eddy-current inspection uses electromagnetic induction to detect flaws in conductive materials. A circular coil carrying current is placed in proximity to the test specimen (electrically conductive). The alternating current in…

Discontinuities in Ultrasonic Testing in NDT
This blog will discuss types of discontinuities that can be evaluated with the ultrasonic testing in NDT method. Discontinuities can be divided into three general categories inherent, processing and service Inherent discontinuities are usually formed when the metal is molten. Inherent wrought discontinuities relate to the…

What is Ultrasonic Thickness Testing ?
Ultrasonic Testing Ultrasonic Testing utilizes high frequency sound waves which are not audible to human ears. The Ultrasonic sound waves are used for measurements of thickness of any material. General frequency used in ultrasonic thickness measurements probe is 5 Mega Hertz and above. The probe is placed over…

Ultrasonic Testing for materials
What is Ultrasonic Testing? ULTRASONIC TESTING is a method for sending ultrasound into material and analyzing the returning sound waves for defect free components. It use scanning devices called probes. After application of Couplant over the material surface probe is place over the material. The sound travels…
