Application of Simple Numerical Simulation of Welding Distortion Using Thermal Shrinkage Technique to Multi-layer Welded Joint

The thermal shrinkage technique with previously proposed input parameter values for single-pass welding was applied to a multi-layer butt-welded joint four layers and six passes validate whether these parameters are applicable welded joints. out-of-plate displacement distributions of the obtained using were in good agreement those elastic-plastic analysis an experiment. angular distortion transverse at center line well agreed experimental results each pass. Furthermore, calculation time 1/6 that analysis. Our demonstrate could be
