대입열 용접에 의한 HAZ연화부를 갖는 극후판 용접이음부의 인장강도 평가
Tensile strength of thick plate welded joint with weld HAZ softening for hight heat input welding
- 발행 : 2006.05.01
초록
In recent time there are vigorous requirement for the use of thick steel plate in various industrial fields including shipbuilding industry. Application of TMCP steel plates, especially, is increase progressively. As a welding process for thick steel plate assembly high heat input welding method is used. However, HAZ softening of TMCP steel plates has a possibility to reduce the strength of welded joint. In this study, therefore, tensile strength of TMCP welds had softened HAZ was examined using numerical calculation and experiment.
