Welding inspection Methods
Welding is a process of joining metals by process of heating. Most of the weld made are manual. It is possible that the weld may have various defect formation due to parameters of welding and poor workmanship. Why is Welding Inspection Methods important? Therefore the weld…

Procedure for Liquid Penetrant examination
LIQUID PENETRANT EXAMINATION (PT) Pentrant Testing is surface defects detection method, the method can be used on any material ( i.e: Ferrous/ non-ferrous, conductive/ non conductive, metals/ non metals) But PT is limited to materials having porous surface or very rough surface. PT can be carried out…

What is eddy current testing in NDT?
What is an Eddy Current? Eddy currents are currents that circulate in conductors like swirling eddies (a whirlpool) in a stream. They are induced by changing magnetic fields and flow in closed loops, perpendicular to the plane of the magnetic field.

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…
