A method of using hot isostatic pressing to join metallic members that form a component in a gas turbine engine is disclosed. The method includes applying a surface treatment to the outer surfaces (14, 15, 22, 24) of first and second metallic members (12, 18) based on whether a mechanical or metallurgical joint for the component is desired. Additionally, the method includes aligning the outer surfaces (14, 15, 22, 24) of the first and second metallic members (12, 18) to create a sealed cavity, which encompasses the joint, between the first and second metallic members (12, 18). Once the outer surfaces (14, 15, 22, 24) are aligned, the method includes subjecting the members (12, 18) to hot isostatic pressing such that material from the first metallic member (12) flows into a recess (26) within the second metallic member (18) so as to join the first and second metallic members (12, 18) to form a consolidated component (10). The consolidated component (10) may then be machined and finished (316) for use in a turbine engine. |
