The invention relates to a blade and to a rotor for a gas turbine and to a method for linking the blade parts of a gas turbine. The invention provides a blade section (1) and at least one additional blade part (4, 16, 21). Said blade section (1) is provided with at least one front connecting surface (2, 3) and the additional blade part (4, 16, 21) with a front connecting surface (6, 18, 24). An inductor (10) is arranged adjacent to the connecting surfaces (2, 3, 6, 18, 24) of the blade section (1) and the second blade part (4, 16, 21). The connecting surfaces (2, 3, 6, 18, 24) of the blade section (1) and of the additional blade part (4, 16, 21) are positioned substantially in alignment and at a certain distance to one another. The blade section (1) and the second blade part (4, 16, 21) are welded together by excitation of the inductor (10) with a high-frequency current and by joining them and contacting their connecting surfaces (2, 3, 6, 18, 24). |
