Nd:YAG LB 와 GTA 를 of용한 핵연료봉의 Zircaloy-4 봉단용접특성에 관한 연구
A Study on the Characteristics of Zircaloy-4 End Cap Welding of Nuclear Fuel Pin Using Nd:YAG LB and GTA
초록
This study is to compare the weldability of Zircaloy-4 end cap of nuclear fuel pin using by GTA and Nd :YAG LB. The welding parameters which affect bead width and penetration depth have been investigated. The effect of joint geometry of end cap for GTAW and LBW has been studied and optimum conditions of Zircaloy-4 endcap welding have been found. Microstructures and microhardness of GTA and LB welded zones have been also compared.
