| Abstract Scope |
In recent years, high-frequency impact treatment (HFIT) has been used as a reliable, effective and user-friendly method for improving the post-weld localized fatigue strength of welded structures. High frequency impact treatment reduces the stress concentration in the weld zone and increases the fatigue strength of the material by generating residual stresses in the compressive direction. In this study, it is aimed to increase the mechanical strength of the welded areas with MIG welding method used in overhead cranes by using HFIT method. In this context, fatigue and mechanical characterization tests were performed with newly developed test specimens to test the fatigue life and the conditions before and after HFIT were compared. After the comparison, it was determined by physical tests that the mechanical strength of the weld area increased with the targeted output. |
