Abstract
Abstract 1. Process for joining components (1, 1A, 1B), consisting of a highly heat-resistant oxide dispersion-hardened alloy based on nickel or iron, by means of diffusion welding, characterized in that the alloy of the components (1, 1A, 1B), which are to be joined, is welded in its fine-grained, not recrystallized initial state at a temperature between 800 and 1100 degrees C and under a pressure of 1 to 200 MPa, and that the workpiece produced in this way is subjected after welding to a heat treatment in such a way that recrystallization across the joint face takes place.
