Investigating the Residual Stresses During Angular Hard Facing of Mild Steel

Abstract

In this study, permanent stress and deformations resulting from angular weld seams of the hardfacing process in flat plates were investigated. Temperature distributions, stress distributions, and permanent deformations were calculated in the study carried out with the finite element method. Experiments in the literature were used for validation. A very high agreement was obtained between the experimental and model results. Since only longitudinal and transverse welds were examined in previous studies, how angular welds will affect stress and deformations has been demonstrated in this study. In addition, the changes in stresses were calculated considering the cooling time after the welding process. Among the findings, it has been observed that long weld seams cause higher temperatures, deformations, and stresses. In addition, after cooling, it is seen that the stresses increase even more in terms of both tension and compression.
