Abstract
Distribution and dispersion of residual stress at butt-welding joints of pressure boundary piping made by several welding conditions were evaluated by experimental measurement and FEM analysis. Effect of welding conditions of final welding layer such as welding speed and heat input on residual stress at butt-welding joints was discussed in detail.
