The production mechanism of out-of-plane deformation (longitudinal bending deformation and angular distortion) was investigated. The shape of longitudinal bending deformation was determined by the relative position of the neutral axis for the cross section in fillet welding and the welding heat source. That is, when the neutral axis is above the welding heat source, the shape becomes convex, and when the neutral axis is below the welding heat source, the shape becomes concave. However, even if the position of the neutral axis, which was determined only by the cross section of the object, and the position of the welding heat source coincided, a small longitudinal bending deformation was generated because the central position for expansion and shrinkage did not coincide with the neutral axis of the object. The magnitude of longitudinal bending deformation was influenced by the web height, the distance between the neutral axis and the welding heat source. In angular distortion, the shape of the deformation was determined by the relative position of the neutral axis for the cross section of the flange and the welding heat source. That is, when the welding heat source exists on the flange surface, V-shape angular distortion was generated. The magnitude of deformation was influenced by the flange thickness and the welding speed. The generality of the production mechanism of out-of-plane deformation generated in fillet welding was confirmed.
