Eddy Current Saturation Testing
Eddy current saturation testing magnetizes a workpiece to eliminate permeability variations and enable accurate measurement of conductivity and coating thickness.
Physical-Chemical Mechanism of Action
Eddy current saturation testing uses an external magnetic field to fully saturate the workpiece magnetically. This eliminates local permeability variations and allows precise measurement of electrical conductivity and coating thickness.
Metallurgical Relevance & Welding Risks
If measurements are inaccurate, variations in the material structure can cause errors. Saturation testing ensures the measurement is correct and free from misleading results.
Workshop Practice & Action Instructions
1. Set up the workpiece for eddy current testing.
2. Activate the magnetic field and saturate the workpiece completely.
3. Measure electrical conductivity and coating thickness according to the specified procedures.
