The Analysis of Hydrogen Diffusion under Heat Transfer Condition around the Heat Affected Zone of Welding

Abstract:

Hydrogen embrittlement causes a crack initiation and brittle fracture. Therefore, it is important to conduct theoretical analysis to predict hydrogen distribution on the basis of reasonable physical model. In this paper, numerical analysis on the hydrogen diffusion and concentration at the localized stress field was conducted to clarify the behavior of hydrogen concentration and the sensitivity of hydrogen embrittlement. Furthermore, on the basis of this analysis, the effect of post weld heat treatment on the release of concentrated hydrogen was analyzed and optimum condition of post and pre heat treatment on the welding was investigated.
