Zusammenfassung:	PURPOSE:To save welding metal and alleviate welding deformation by changing the welding quantity of a steam outlet side welding part for a backplate and web plate, forming a hollow nozzle wing, correspondingly to a quantity required for each section. CONSTITUTION:The welding quantity for each section is changed by welding a steam outlet side welding part 4 of a backplate 2 and a web plate 1, composing an hollow nozzle wing, through one pass of a continuous one layer and changing the width of weaving according to the quantity of welding metal required for each section of the nozzle wind. Thus, the welding metal is saved and the welding deformation can be alleviated.
