레이저 용접 공정 시 발생하는 잔류 응력에 저감 방법에 대한 연구 = Study on reduction methods of residual stress in laser welding process

다국어 초록 (Multilingual Abstract)

The demand for the increase of the welding quality such as optimized welding process control, The study on the prediction and evaluation of residual stress among the research to improve the quality of laser welding process and increasing the mechanical property are not yet satisfied compared with their importance. The simulated results could be applied to estimate a peening effect, when a different confinement was used in the laser shock peening process. The residual stress could be formed by the depth of the proposed method of reducing the residual stress is performed in the optimal condition. The welded structures and products during the production process increase the mechanical property of repeated stress, which could be expected to extend the fatigue life of the structure.
