Abstract

PURPOSE: To increase the strength against the corrosion fatigue of a cover plate by providing a reinforcing layer of stainless steel on the inside of the cover plate near the welded part between the cover plate and a rib plate.
CONSTITUTION: A reinforcing layer of a stainless steel 11 is provided on the inside of a cover plate 3 near a welded part 4 between the cover plate 3 and a rib plate 2. This construction permits to reinforce a part of comparatively high stress by the stainless steel 11, and consequently increase the strength against the corrosion fatigue of the cover plate 3.
