Finds cracks and surface defects at welds, through paint.
A 32-element eddy current array that sweeps a full band in one pass and pins every indication to its location: weld toes, nozzle collars, plate. At walking pace, through paint.
Thirty-two elements cover a full band in a single pass and report surface-breaking and near-surface discontinuities.
The eddy current array sweeping a steel surface: the coils' fields, and an indication lighting up where the surface breaks
The eddy current array sweeping a surface, lighting an indication where it breaks.
Surface-discontinuity screening
Limits
ECA reads the surface and near-surface only, and reports indications rather than sizing them.
