Fillet welded T-joints with the low-transformation-temperature welding wire was fabricated under conditions that the generation of the angular distortion was prevented. In one condition of restraint, the T-joint was welded with its flange plate fixed by clamping tools during welding and released after the joint was cooled to the room temperature. In the other condition, rib-plates were arranged orthogonal to the welding direction to prevent the generation of the angular distortion. Numerical simulations of these two joints were also carried out. Results of numerical simulation showed that the transformation expansion of the weld metal was effective for reducing the angular distortion even under the restraint conditions.
