| Sumario: | Although welding operations are mostly carried out in atmospheric conditions in shipbuilding, underwater welding is also used intensively in order to speed up the repair processes in the underwater parts of the ships. It is known that due to the nature of the underwater welding, there are significant differences in the weld area compared to the weld made under atmospheric conditions. The most important factor that creates this difference is that the cooling rates achieved after welding contain significant differences compared to welding performed under atmospheric conditions. On the other hand, it is known that the depth of the underwater welding has a significant effect on this cooling rate. In the literature, it is seen that studies on underwater welding are extremely limited. On the other hand, no study has been found that has examined the effect of depth on the microstructure and mechanical properties during underwater welding of steels used in shipbuilding. In this context, in this study, a steel used extensively in shipbuilding was joint with atmospheric conditions welding and underwater welding (two varying depths), and the microstructure and mechanical properties of the welded area were examined comparatively. |
