Surface Eddy Current Crack Detection

TechCorr delivers high-sensitivity Surface Eddy Current Testing (ECT) for the detection and characterization of surface-breaking and near-surface discontinuities in critical conductive components. Engineered as a fast, clean, and reliable alternative to liquid penetrant and magnetic particle testing, surface eddy current utilizes electromagnetic induction to detect fatigue cracks, weld fissures, and stress corrosion cracking. Because eddy current operates through non-conductive paint, epoxy, and protective coatings up to several millimeters thick, assets can be inspected immediately without requiring sandblasting or chemical coating removal.

Key Capabilities

• Detection of surface-breaking fatigue cracks, heat-affected zone fissures, and stress corrosion cracking in high-stress infrastructure.
• Quantitative depth sizing and length measurement of discovered defects to support immediate structural Fitness-for-Service analysis.
• Non-contact inspection capability scanning directly through non-conductive coatings, paint systems, and marine preservation layers.
• Rapid application on complex geometries, structural node welds, vessel nozzles, turbine blades, and bolt hole configurations.
• Integration with rope access mobility to execute crack inspections on elevated offshore structures, crane booms, and flare risers.

Compliance & Standards

Testing procedures, personnel qualifications, and defect evaluations meet stringent engineering codes including ASME Section V (Article 8), ASTM E376, ASTM E426, ISO 12718, ISO 15549, and API 510/570/653 in-service inspection criteria. Personnel are qualified under ASNT SNT-TC-1A, CP-189, or ISO 9712 standards.

By eliminating coating restoration expenses and hazardous chemical solvents, TechCorr’s surface eddy current crack detection provides rapid, repeatable flaw verification that minimizes equipment downtime while preserving the structural integrity of core assets.
