Overlay 용접을 통한 원전 이종 금속 용접부 잔류응력 완화효과에 대한 연구
A study on the residual stress relieving for dissimilar metal weld under weld overlay
- 발행 : 2007.11.15
초록
In nuclear power plants, residual stress of dissimilar metal weld propagates cracks in the weld metal which is susceptible to stress corrosion cracking. Overlay welding is a process widely used to mitigate residual stress replacing inside tensile stress by compressing stress. The purpose of this paper is to predict the effect of weld overlay by finite element analysis.
