| Abstract Scope |
Fabrication and welding of structural components for the hot section of gas turbines continues to be of high importance to the manufacturing industry within this discipline. Weld cracking and specifically hot cracking as well as strain age cracking, is a serious concern during fabrication of these structural components. The aforementioned cracking phenomena can occur during welding or subsequent heat treatment of precipitation hardened Ni- based superalloys and can be influenced by i.e. chemical composition in terms of hardening elements and impurities, microstructure of base material and weld zone, together with welding processes and corresponding parameters and heat input. This paper discusses and reviews the literature with regard to cracking susceptibility of wrought, cast as well as superalloy parts produced by additive manufacturing.
