Welding distortion of a T-joint is calculated numerically considering the effect of phase transformation. Welding distortion becomes smaller in the case of a T-joint with developed low-transformation temperature welding wire than with conventional wire, which has been produced for high accuracy fabrication. Results of weld distortion history by numerical simulation agree well with those by the measurement during the whole weld process. The effect of material properties such as martensitic transformation temperature on welding distortion is investigated by using numerical simulation.
