Component and method for joining metal elements

摘要

A component, in particular a component of a gas turbine, is described composed of at least two metallic structural elements, the first structural element having a first joining surface, and the second structural element having a second joining surface, and the structural elements being joined via their joining surfaces by an inductive high-frequency pressure welding. One of the joining surfaces is shaped to widen peripherally in comparison to the other joining surface, and an upsetting deformation produced in a join region in response to the joining of the structural elements rests virtually entirely within and, in particular, on a peripheral collar formed by the peripheral widening of the one joining surface. A method is described for joining metallic structural elements, in particular structural elements of a gas turbine, an inductive high-frequency pressure welding being used to join corresponding joining surfaces of the structural elements.

1. A component comprising at least two metallic structural elements, a first structural element having a first continuous joining surface, and a second structural element having a second continuous joining surface, the first and second structural elements being joined via the first and second continuous joining surfaces by an inductive high-frequency pressure welding,
wherein the first continuous joining surface has a shape that is peripherally widened in comparison to the second continuous joining surface, and an upsetting deformation produced in a join region in response to the joining of the first and second structural elements rests virtually entirely within and on a continuous peripheral collar formed by the peripheral widening of the first continuous joining surface; and wherein at a junction of the second continuous joining surface and the first continuous joining surface, the upsetting deformation has a notch; the notch residing outside of a nominal geometry of the first and second structural element of the component.
