ABSTRACT:
In a repair method for lengthening turbine blades having undersized blade lengths, a sheet metal strip is preformed in a U-shape and is then used as a support form, for which it is tightly pressed against the upper blade contour in a force-locking and exactly contour-fitting manner by an outer synthetic material surround molding. The sheet metal strip is arranged in such a manner that it protrudes beyond the blade tip and protrudes out of the pressing synthetic material mass. In order to lengthen the turbine blade, the space within the sheet metal strip that protrudes beyond the blade tip is filled by laser deposit or build-up welding. Furthermore, a particular support form is provided for carrying out the lengthening of the turbine blade, and a method for producing the support form is described.
