Abstract

In previous report, a new method was introduced for obtaining residual stress distributions in welds qualitatively by measuring surface relief induced due to cutting and annealing.
This paper presents the micro-distributions of residual stress in welds obtained by this new method in four kinds of steel having a different transformation characteristics.
Based on these test results, some considerations are performed on the micro-mechanism of welding residual stress, and it is clarified that a cause of reheat cracking by a subsequent welding pass occured in multi-pass weld of high strength steels.
