摘要

The micromagnetic measurement method is a fast and easy to handle alternative for the determination of residual stresses in steel welds. The accuracy is lower in comparison to diffraction techniques but it can be applied faster and under rough conditions however connected with a lower accuracy. Experimental results of investigations with different steel welds show that the method requires an external calibration and the consideration of particular boundary conditions as well as certain limitations must be accepted. Then the method is a good alternative or more a complementary measurement methods which helps to reduce the effort for the analysis of residual stresses in welded components.
