抄録	Unidirectional-solidification and phase transformation in the weld metal of commercial pure-titanium in Gas Tungsten Arc welding was observed by using Time-Resolved X-Ray Diffraction (TRXRD) system with two-dimensional pixel detector. An undulator beam was used as a probe. A larger area of a cone of half apex angle 2θ made by diffracted beam could be detected in the time-resolution of 0.05 seconds, in unidirectional solidification and subsequent phase transformation process of pure-titanium weld metal. The constrained growth of weld metal in solidification processes and rapid change of phase ratio in β-α transformations were clearly shown.
