Abstract

Surface Barkhausen Noise (SBN) generation has been monitored for two different sweep field orientations in a pipeline half-section which was subjected to circumferential tensile and compressive stresses. When the sweep field is oriented in the circumferential direction SBN increases with applied tension and decreases with compression. The SBN signal is more sensitive to tension than it is to compression; this has been explained in terms of a preferred axial domain orientation. Unlike the case of a circumferential magnetic sweep field, neither tension nor compression have a significant effect on the SBN Signal when the field is oriented axially.
