NDT – Ultrasonics

Eddy Current offers important advantages for the detection of flaws in metals and has a very broad range of applications.  It is truly non-destructive, reliably detecting flaws invisible to the unaided eye.  It can penetrate layers of sound material to discover hidden damage which would threaten the serviceability of the material or structure. Applications include: Surface and near-surface flaw detection, Inspection of multi-layer structures, Metal and coating thickness measurement, Metal sorting by grade, heat treatment and hardness, Electrical conductivity measurement.
