Abstract

PURPOSE: To check corrosion at the joint section between the front rim of a rotary blade and the blade accurately by integrating a front rim corrosion preventive section and a cover section as a corrosion preventive piece deposited on the front tip rim of the blade.
CONSTITUTION: A corrosion preventive piece 10 is composed of a front rim preventive section 16a mounted to the front rim of a rotary blade to check corrosion and a flat cover section 16b which is connected to a blade cover 10a provided at the tip of the blade 10 to form the front rim thereof. The two component are integrated with a smooth curvature on the external surface of the boundary portion 16c. In addition, a corrosion preventive section 16a of the corrosion preventive piece 16 is engaged in layer with a notched step 10b of the rotary blade while the cover section 16b of the corrosion preventive piece is joined with the front of the blade cover 10a. Then, they are welded together along the weld line 17. This eliminates deposited metal in the area susceptible to corrosion, thereby checking corrosion of the front rim.
