The process consists of casting a hollow blade (1) from a nickel alloy with at least one side wall (2, 3) and an open tip, making a plate of a laminated material with at least one layer of the same metal as the blade and a layer of a brazing material, brazing the plate onto the tip of the blade by the application of pressure, and machining it e.g. by electro-erosion into a bathtub-shaped recess with a base (8) and rim (9, 10). The laminated plate is preferable cut out by water jet to avoid the creation of uneven zones, and its brazing material layer is made e.g. from nickel, chrome or boron.
