A Study on Friction Welding and AE Evaluation for Cold Die Steel and High Temperature Creep Properties
금형강의 마찰용접과 AE평가 및 고온 크리프 특성에 관한 연구
Abstract
This paper deals with determining the proper friction welding condition and analyzing various mechanical properties of friction welded joints of the bladepart heat resisting steel(STD11) for cold die punch to the shank part alloy steel(SCM440). And the in-process real-time weld quality evaluation technique by acoustic emission during friction welding of STD11 to SCM440 steels with higher confidence and reliability has been much required even though it might be the first trial approach for developing it. Also, the high temperature properties of STD11-SCM440 weld were considered in this paper.
