摘要：

Residual stresses in ferromagnetic material affect the direction and structure of domains and generate the magnetic flux abnormality on the surface. Three-dimensional magnetic field on the surface of a circular-welding pipe specimen was inspected with 8 mm lift-off before and after low-temperature annealing aimed for residual stress releasing. Small hole stress testing was also carried out with a contrast to the magnetic testing before annealing. The magnetic field characteristics and the residual stress distribution were compared and discussed. The normal component of magnetic field correlated with residual stress. The magnetic field abnormality on ferromagnetic material could be used for residual stress inspection. (C) 2002 Elsevier Science B.V. All rights reserved.
