Abstract: The testing method of steel pipe seam based on the theory of magnetism leakage is be concerned. The relevant mathematical model is presented for the distribution of magnetic field covering magnetic section of steel pipe seam. According to Schwarz-Christoffel transformation theorem, We have derived theoretical results, which are the bases for analysing the sensor's exciting structure and the distrubtion feature of testing element.
Key words: Seam, Steel pipe, Test of magnetism leakage
