Eddy-current testing (ET) is one of many electromagnetic testing methods used in nondestructive testing making use of electromagnetic induction to detect and characterize surface and subsurface flaws in conductive materials.

When it comes to surface applications, the performance of any given inspection technique depends greatly on the specific conditions, mostly the types of materials and defects, but also surface conditions, etc.

Alternating Current Field Measurement (ACFM):

It is an electromagnetic technique for NDT detection and sizing of surface breaking cracks. It was derived from the methods used in eddycurrent testing and works on all metals, ferrous or non-ferrous. Since it doesn't require direct electrical contact with the surface it can work through coatings such as paint or rust.

The method both detects cracks and estimates their size and length. It can inspect any electrically conductive material. Data is recorded electronically for off-line evaluation if necessary and provides a permanent record of indications.

The method and can carry out inspection without removing any protective paint coating. With suitable probes, the method can be used on hot surfaces.

Other Services:

Heat Treatment:

Post Weld Heat Treatment (PWHT) reduces the residual stresses formed during welding. It also restores the macro structure of the steel. Mandatory in high pressure applications, constructors have to strictly follow PWHT requirements to avoid component failures

PWHT eliminates the effects by heating, soaking, and cooling the weld area in a controlled manner to temperatures below the first transformation point, giving the macro structure sufficient time to readjust to its original state and removing the residual stress.

Hardness Testing

The Leeb rebound hardness test method was developed to provide a portable hardness test for metals. It was developed as an alternative to the unwieldy and sometimes intricate traditional hardness measuring equipment.

Traditional hardness measurements like Rockwell, Vickers, and Brinell, are stationary, requiring fixed workstations in segregated testing areas or laboratories and these methods are selective, involving destructive tests on samples. The portability of Leeb testers can sometimes help to achieve higher testing rates without destruction of samples, which in turn simplifies processes and reduces cost.
