Pulsed Eddy Current Spectroscopy
Eddy current pulse spectroscopy is a testing method that uses broadband magnetic field pulses to determine the depth of material damage or wall loss.
Physical-Chemical Mechanism of Action
This method uses electromagnetic pulses to penetrate a material and analyzes the reflections of the waves off flaws or interfaces. The time it takes for the signals to come back tells you how deep the anomalies are.
Metallurgical Relevance & Welding Risks
This technique is especially useful for checking weld quality and detecting zinc loss or corrosion. Wrong interpretation can give you inaccurate results, which leads to wrong conclusions about material integrity.
Workshop Practice & Action Steps
To use this method correctly, you have to calibrate the magnetic field pulses precisely and keep careful track of test times. Applying it requires specialized equipment and signal analysis know-how.
