Abstract

High strength steel welding joints fatigue strength could be improved by changing the as weld condition with post-weld treatment. These post-weld treatments are classified to two categories which are the weld geometry and residual stress condition improvement methods. Post-weld treatment methods of high strength steel welding joints by improving weld geometry were overviewed in the first part of our article. The post-weld treatment methods for improving the welding joint residual stress condition are also applicable in high strength steels, but some consideration have to take in place when applying these techniques. The aim of this paper to review the welding joint residual stress condition improvement techniques considers application of these techniques in high strength steels.
