Abstract

Haynes214 alloy should be welded together with other alloys when it is used as brush seal materials. In the present investigation the welding performance of Haynes214 alloy welded with GH4169 alloy and GH625 alloy was carried out. The microstructure and mechanical properties of the welding joint under different conditions were studied. The results showed that no liquation crack or other defect existed at the welding joint of Haynes214-GH4169 and Haynes214-GH625. After aging, the room temperature tensile strength of Haynes214-GH4169 and Haynes214-GH625 welding joints was approximately 94% of Haynes214 alloy. The high temperature (500 °C) tensile strength of Haynes214-GH4169 welding joint was about 85% of Haynes214 alloy, while Haynes214-GH625 welding joint was about 75% after aging.
