Abstract Scope |
Superalloys are materials with unique characteristics, not at least with regard to their superb temperature capability and strength in relation to ordinary materials such as stainless steel. The superalloys are readily used in aero-engines and specifically the hot section which serves as the most challenging application. It is therefore of high importance that the welds used in the design are of suitable quality to account for the demanding environment. Despite these challenges, fabrication in which welding is commonly utilized is being more and more employed to tailor structural fabrications in an improved manner to reduce weight as well as to increase performance. Two new superalloys, G27 and VDM780, have been developed with matching and improved properties to the well-known Alloy 718 and Waspaloy. This presentation will provide advice and information on welding and weldability aspects of Ni- and Ni-Fe-based superalloys in general and G27 as well as VDM780 in specific. |
