Abstract

See full text

The invention relates to a non-destructive inspection method using eddy currents for detecting flaws in a metal structure (3) by means of an array (5) of coils attached to a surface (31) of said structure (3) comprising activation of the coils, measurement of the electrical signals representative of the eddy currents, and evaluation over time of a variation in the electrical signal of each of the coils (511-536) by taking as a reference an edge effect corresponding to a specific electrical signal emanating from at least one coil installed at the edge of the surface, the level of said variation being indicative of the presence of the flaws in the structure.
