The influence of the solid state phase transformation on welding deformation of low alloy high strength steel

摘要

The conclusions of this study are summarized as follows. 1. In one-side fixed welding of thin plate, the unfixed side warps a lot, especially at the position in the middle. 2. The deformation appears to be an increase-decrease- increase process, either in the experiment or in the calculation, no matter if we take account of phase transformation. 3. Phase transformation from austenite to phases at a lower temperature decrease the welding transformation.
