ET – EDDY CURRENT

ET – EDDY CURRENT TESTING METHOD

Eddy Current method is used to detect irregularities and discontinuities for both surface and subsurface defects. This technique utilizes the phenomenon of electromagnetic induction. The depth of penetration depends on electrical conductivity of the material, magnetic permittivity, the size of the part and its shape, as well as the frequency of the eddy current that is being used. ET is widely used during pipe, storage and pressure containers, rails inspections, as well as checkups of various parts and elements. Eddy current methods allow to detect any decrementation of wall thickness (along with indications of its location either from the inside or outside) caused by erosion or corrosion as well as deformations, cracks, perforations and other material inclusions.

APPLICATIONS OF EDDY CURRENT TESTING

• materials conducting electrical current
• detection of surface defects – this method is ideal for detection of defects that are reaching surface – hence its called the best alternative for PT (FPI) and MT (MPI) methods
• hardness measurement – for example. testing of parts on the production line to check whether the hardness is appropriate with the order
• inspection of material quality – the results can easily be compared to reference materials for general information on quality of the used material
• thickness inspection of the tested elements
• detection of non metallic inclusions – checkup for any material deviations against reference parts

ADVANTAGES OF EDDY CURRENT TESTING

• non contact method
• allows for automated form of surface defect detection – alternative for PT and MT methods
• high sensitivity and repeatability of detection for even the smallest of cracks (with few μm of depth)
• price competetive – in comparison to the ammount of elements that are controlled
• environment friendly
• fast – considering the speed of testing of single element in comparison to other methods
• easyt to keep track of and archive the results

PRODUCERS OF EQUIPMENT AND SYSTEMS FOR EDDY CURRENT TESTING

We are distributing the highest class of equipment for eddy current method of non destructive testing from the world renowned producers such as Rohmann GmbH. They have worked hard to develop pioneering and innovative technologies for testing during production and inspection of surfaces being in use.

ROHMANN GmbH was founded in 1977 with a staff of two to solve special applications in the aviation industry.1959
The first big success in the market was the introduction of the ROTOTEST B500, the world’s first battery-powered test instrument with display for rotary probes that same year.

The company’s success and growth continued in 1987 with the introduction of the ELOTEST B1, a universal eddy-current test instrument for the manual inspection of safety-relevant components in the aerospace industry. The instrument became the global standard for battery-powered eddy-current instruments. Until today, more than 1,000 instruments have been sold worldwide.

In 1989 the introduction of the ELOTEST PL.1 marked the successful entry into the market of production-line inspection.

In 1999 they developed the HARMONIC 2000, the first fully digital high-perfomance test instrument to inspect heat exchangers in cooperation with Framatome. That same year the ELOTEST B300 representing the third generation of battery-powered eddy-current test instruments made its debut.

One year later the ELOTEST M2, the world’s most powerful one-hand universal test instrument was introduced.

And they continue with full speed ahead.
