To suppress deterioration in the shape accuracy of a vehicular structure member, which is caused by influence of thermal distortion of a plate material, by welding a reinforcement material on both front and rear surfaces of the plate material by means of laser cladding for the plate material composing the vehicular structure member.SOLUTION: In a vehicular structure member 10 composed of a plate material 10A and formed by linearly extending and welding a reinforcement material 14 on a plate surface of the plate material 10A by means of laser cladding, the reinforcement material 14 is formed on both front and rear surfaces 12A, 12B of a vertical wall portion 12 of the vehicular structure member 10 a cross-section of which is shaped like a hat.SELECTED DRAWING: Figure 1
【課題】車両用構造部材を構成する板材に対するレーザークラッディングによる補強材の溶着を、板材の表裏両面に施すことにより、板材の熱歪みの影響で、車両用構造部材の形状精度が悪化するのを抑制する。【解決手段】板材10Aにより構成され、板材10Aの板面上にレーザークラッディングにより補強材14が線状に延びて溶着して形成された車両用構造部材10であって、補強材14は、断面ハット形状の車両用構造部材10の縦壁部12の表裏両面12A、12Bに形成されている。【選択図】図1
