Evaluation of the Welding Zones’ Magnetic Anisotropy by Using Magnetic Barkhausen Noise

Abstract:

The present paper investigates the utilization of the magnetic Barkhausen noise method for the experimentally, nondestructive characterization of the magnetic anisotropy phenomenon, in a welded pipeline steel. The results shown that it is possible to distinguish the three welding zones in the curve of the anisotropy coefficient
