EDDY CURRENT ARRAY

Examination of welds and plates by “Eddy-current” for the detection and dimensioning of cracks, through the use of special equipment and probes, according to the EN1711 standard “Non-destructive examination of welds – Eddy current examination of welds by complex plane analysis” and ASME V Article 8 Eddy Current Examination of Tubular Products;

MAIN ADVANTAGES

– Less demanding surface preparation;
– Does not require paint removal;
– Does not require consumables;
– Does not require utilities (water, energy or compressed air);
– No filter required;
– Fast, clean and effective process;
– Faster than magnetic particles and liquid penetrant;
– Allows recording of calibration and inspection, and consequently the monitoring of the evolution of discontinuities;
– Advantages under the ACFM / Liquid Penetrant and Magnetic Particle tests (see additional documents “ACFM x EC” and “EC x PM_LP”);
– Eliminates noise caused by corrosion;
– High POD (Probability of Detection);
– Minimal analysis is required with real-time records;
– It is possible to measure the depth of discontinuities.

LIFT OFF COMPENSATION

Lift Off compensation helps to reliably measure the depth of discontinuities:

– For welds;
– Corroded surfaces;
– Painted surfaces;
– Stress corrosion;
