Best Eddy Current Testing of Saudi Arabia & UAE - Eiwaa Group Eddy Current Testing or Eddy Current Inspection is used for the detection of surface breaking/cracks and near surface planar defects in welds, heat affected zone and parent material. EIWAA offers eddy current testing applied on coated and uncoated objects &the eddy current testing can be carried out on all accessible surfaces on welds of almost any configuration. Minimum Surface preparations is required for the eddy current testing. Depending on the sensitivity requirements, Eddy current inspection is able to detect surface cracks through non metallic coating of up to 2mm thickness.
Eddy Current Inspection and testing equipment shall be able to operate the frequency range of 1 KHz to 1 MHz. For the Eddy current testing instrument calibration at site, a calibration block of same type material shall be used for calibration . Eddy Current Testing instrument calibration block have EDM Notches of 0.5 mm,1mm and 2 mm depth; unless otherwise agreed between contracting parties. Non metallic stripes of a known thickness to simulate the coating or actual thickness on the calibration block shall be used. Current inspection of welds in ferritic materials, the frequency shall be chosen according to the material (conductivity, permeability),the defect(type, location and size)and the probe design.
Its suggested to use a frequency around 100 KHz. The minimum size of indication that the eddy current method is capable to detect in ferritic steel weld in the as welded condition is
