The effect of bonding temperature, time, pressure and PBHT (Post Bonding Heat Treatment) on the bonding of Inconel 718 to itself was assessed. A post bonding heat treatment (PBHT) is helpful and crucial to produce a sound joint. The influence of pressure was studied for the bonding of Inconel 718 to 17-4 PH stainless steel. FEM (Finite Element Method) was carried out to assess the residual thermal stress. For the bonding of ODS alloy - Incoloy MA 956, in addition to the influence of bonding pressure, temperature and time, the influence of surface roughness was examined.
