摘要

The welding is a technique for connecting two materials by partially heating and melting. Therefore, the welding deformation is inevitably caused by thermal expansion and shrinkage non-uniformly caused. It is important for the quality control of the welding member to understand the deformation and the strain that arises on the surface of the steel member while welding. In this study, the deformation and the strain behavior caused on the surface of the steel member in welding and cooling process were verified by digital image correlation method (DICM) and 3D thermal-elastic-plastic FE analysis.
