Abstract

PURPOSE: To perform diffusion welding perfectly without causing deformation through direct welding by heating joining materials to their recrystallization temperature or more and pressing them then releasing the pressure and elevating their temperature to a high temperature below their melting point and holding said temperature for a fixed time.
CONSTITUTION: Coupling materials are heated to their recrystallization temperature (the lower recrystallization temperature with dissimilar material joints) in a vacuum or inert gas atmosphere and they are pressed under said temperature. Thence, in succession to this, or after the temperature is once lowered, they are reheated at a high temperature below their melting point in the state released from pressure, whereby diffusion welding is completed. In this case, the heating atmosphere is kept vacuum or inert gas atmosphere throughout this process. As a result of this, extremely superior joining results are obtainable without using any insert material or the like for promotion of bondability at all and without causing any deformation in direct joining.
