Abstract-This paper investigates the induced angular distortions due to single pass welding process on butt joint. The workpiece material is low Carbon steel with the dimension of 100 mm x 150 mm x 4 mm (w x I x t). Two different FE methods were investigated to analyze the distortion, namely based on linear thermo-elastic shrinkage using WELD PLANER Ver. 1.2 and based on thermo-elastic plastiā¦
