Abstract
Marine propeller is one of the most important element of ship, it must be taken care of design and maintenance of it. It is inevitable that corrosion pits have occurred on the marine propeller. If corrosion pits have occurred on the blades, they have been repaired ordinary by simple welding methods in shipyards. It must be that the strength is degraded in this process. In this paper, we represent the improvement method of fatigue strength degraded after repairing pits.
