Determination of the magnetic properties of separate zones of welds and the width of welded joints based on magnetic measurements

The magnetic characteristics of pipe steel specimens containing welded joints of different widths were investigated, both under the conditions of a closed magnetic circuit and using overlaid transducers in the form of a half-closed magnetic circuit. The parameters correlating with the welded joint w...

Summary:The magnetic characteristics of pipe steel specimens containing welded joints of different widths were investigated, both under the conditions of a closed magnetic circuit and using overlaid transducers in the form of a half-closed magnetic circuit. The parameters correlating with the welded joint width were determined. The possibility of using the measured magnetic characteristics for deter-mining magnetic properties of separate zones of a welded joint and the welded joint width was demonstrated.
