Eddy current array (ECA) is a non-destructive testing technology that provides the ability to electronically drive multiple eddy current coils, which are placed side by side in the same probe assembly.
Eddy current array is used in both the aerospace and engineering sectors and offers several advantages:
- Complex shapes can be inspected using custom probes.
- Larger areas can be scanned at high resolutions, in a single-probe pass.
- Flaw detection/sizing improved via C-scan imaging.
Morgan Ward’s technicians commonly use eddy current array both on-site and in our labs to take comprehensive material thickness measurements and in accordance with Boeing aircraft scribe line inspections (NTM 53-30-25) ‘C Scan inspection of skin cracks at doubler edges’ to detect discontinuities such as cracks and corrosion.
Morgan Ward’s technicians are qualified to carry out and advise on eddy current array techniques and custom inspections and can conduct tests on-site globally or at any one of our UK laboratories.
All our inspectors are level II or level III certified to EN4179/NAS410 or PCN, where relevant.
