Abstract

PURPOSE: To facilitate welding operation by enlarging the steam inlet end face of the blade into a staircase-like form, providing the inner end of the juncture face between corrosion-proof piece and blade on a plane crossing the length direction of the blade and making the inner end of the corrosion-proof piece to be as thick as about double the width of fusion of the juncture by electron beam.
CONSTITUTION: A corrosion-proof piece 2 has a length shorter than the entire blade length 17, and its steam inlet end 5 is substantially straight. At the inner end 12 of the corrosion-proof piece 2 a juncture face 13 is spaced apart from a lower blade inlet end 7 by a distance 9. This arrangement facilitate the operation of electron beam welding involving movement along the juncture surface 3 between the outer and inner ends 8 and 12 of the corrosion-proof piece. In order to reduce influence upon the mechanical strength and fluid dynamic performance of the blade it is desirable to reduce the extent 10 of projection at the inner end 12 of the corrosion- proof piece 12, and the width of the inner end is made smaller than the width of the outer end.
