HELIX ECA
A 32-element eddy current array that sweeps a full band in one pass and pins every indication to the exact spot it lives: weld toes, nozzle collars, plate. At walking pace, through paint.
- Screens for surface-breaking and near-surface discontinuities, including weld-toe cracking
- Thirty-two elements cover a full band in a single pass
- Every indication is located and pinned on the 3D model for follow-up
- Validated against engineered cut, void and wrinkle test panels with matching scan heatmaps

Honest limits
ECA reads the surface and near-surface only, and reports indications rather than sizing them.
The rest of the range
Screening, not certification. HELIX screening prioritises where to look next and does not certify to any code scheme. Fitness-for-service remains a regulated engineering assessment carried out by your engineers. Individual technical specifications (HLX-SPC series) are available on request.
