Abstract
Aiming at the deficiencies of the traditional alternating current field measurement probes, it is not suitable for the aluminum alloy pipe detection. A Helmholtz coil-type pipe detection probe and its experimental system are proposed and built. Through the finite element software Comsol, the finite element model of the alternating current field measurement in the axial crack in aluminum alloy pipe detection is established. The distribution and variation law of the electromagnetic field in the pipeline are explored. The characteristic signals and are extracted. And the influence of the length and depth of the crack on the characteristic signal is analyzed. The aluminum alloy pipe detection experimental system is established. The experimental results show that the detection system can realize the full circumferential scan of the axial crack on the inner surface of the aluminum alloy pipe.
