The invention relates to a blade and a rotor for a gas turbine and to a method of joining blade parts of a gas turbine, a blade-body section (1) and at least one further blade part (4, 16, 21) being provided, and the blade-body section (1) being provided with at least one end joining area (2 , 3) and the further blade part (4, 16, 21) being provided with an end joining area (6, 18, 24), an inductor (10) being arranged so as to be adjacent to the joining areas (2, 3, 6, 18, 24) of the blade-body section (1) and of the second blade part (4, 16, 21), the joining areas (2, 3, 6, 18, 24) of the blade-body section (1) and of the further blade part (4, 16, 21) being positioned essentially in alignment with and at a distance from one another, and the blade-body section (1) and the second blade part (4, 16, 21) being welded to one another by energizing the inductor (10) with a high-frequency current and by bringing them together with their joining areas (2, 3, 6, 18, 24) touching one another (FIG. 1). |
