- The welding process and the associated control, to a certain degree, have enhanced remarkably in the last decades. One of the recent processes is keyhole TIG (K-TIG) welding, which allows better control and the capability to use lower heat input and higher power density during the welding compared to the conventional one, being essential when joining sophisticated materials utilized in the hot sections of aircraft engines such as nickel-based superalloys. The recent trend in the fabrication of hot sections of aero-engines has been preferably carried out by joining small pieces of superalloys by the welding process instead of casting a single large component due to several benefits, such as lowering the total weight of the components and improving the design flexibility. VDM Alloy 780, a new polycrystalline nickel-based superalloy with service temperature capabilities up to 750 °C, is a promising material to be employed in the fabrication of hot structural parts of an aero-engine. For aerospace manufacturers, producing a superalloy weld bead geometry that meets stringent quality requirements for aerospace applications is crucial. To do so, understanding the influence of welding parameters on weld geometry becomes indispensable, especially when welding a new superalloy using a relatively new welding technique. Hence, in this article, the influence of K-TIG welding parameters on the weld geometry of VDM Alloy 780 has been investigated.
