Application · Eddy-Current Crack Detection
Eddy-Current Crack Detection
Detect surface and near-surface cracks in conductive parts — manual, portable or fully automated.
The inspection problem
Cracks in shafts, gears, bearings, ground surfaces and welds can be tiny, hidden under paint or coatings, and impossible to catch by visual inspection alone.
Why it matters
In series production, crack detection is what keeps zero-defect targets real — and in maintenance, it prevents in-service failures.
Which method fits your part?
Every method has a sweet spot and a limitation. Choose based on defect, geometry, throughput and access — not on habit.
Portable eddy current
When it fits: Field inspection of welds, structures and aircraft components.
Limitations: Operator skill; conductive materials only.
Automated eddy current
When it fits: High-volume crack detection on rotationally symmetrical parts.
Limitations: Requires part-specific fixturing and setup.
