-Eddy current testing (ET) is a non-destructive testing technique based on electromagnetic induction, used to inspect conductive materials without the need for contact or complex surface preparation.

 

-By applying an alternating magnetic field through a probe, induced currents are generated in the material under inspection. Variations in these currents, caused by discontinuities or changes in the material properties, are recorded and analyzed to detect defects.

 

Applications:

· Detection of surface or subsurface cracks and defects.

· Inspection of welds and critical joints.

· Corrosion and thickness-loss monitoring.

· Measurement of material properties and heat-treatment effects.

· Verification of pipes and heat exchangers.

· Quality control in manufacturing and predictive maintenance.
