Magnetization Pulse Testing
Magnetizing pulse inspection magnetizes ferromagnetic parts with short current pulses to create stationary or residual magnetism test conditions. This prevents thermal overload of the test piece.
Physical-Chemical Mechanism of Action
Magnetizing pulse testing uses short current pulses to magnetize parts. These pulses create a strong magnetic field that aligns the magnetic dipoles in the material. The short duration of the pulses prevents thermal overload of the material.
Metallurgical Relevance & Risks in Welding
This technique is especially useful for parts with complex geometry or high temperature requirements, where conventional magnetization could cause thermal distortion. Incorrect application can lead to inaccurate test results and potential misunderstandings in the shop.
Workshop Practice & Instructions
Use magnetizing pulse testing on parts with complex geometry or high temperature requirements. Make sure the current pulses are short and strong to avoid thermal overload. Adjust pulse duration and amplitude according to material and test conditions.
