Residual stress generated in manufacturing did not influence out-of-planedeformation, residual stress and plastic strain produced by welding. The shape and magnitude ofdeflection generated in manufacturing considerably influenced out-of-plane deformation produced bywelding. However, they did not influence residual stress and plastic strain. If the total heat inputwas same, the welding speed did not influence out-of-plane deformation, residual stress and plasticstrain produced by welding. The heat input which is decided for the plate thickness did not influenceout-of-plane deformation, residual stress and plastic strain produced by welding.Keywords:
