DEPOSITION METHOD OF WELD COMPONENT, RESIN COMPONENT USED FOR THE METHOD AND DEPOSITION DEVICE OF WELD COMPONENT

PROBLEM TO BE SOLVED: To provide a deposition method of a weld component capable of securing bond strength of members each other even without using materials with prescribed absorbance and making appearance quality good, a resin component used in the method and a deposition device of the weld component.SOLUTION: A deposition method prepares a first member 210 and a second member 220. The first member has a first thick part 211 and a thin part 212 having different thickness, a flat joint surface JS in one side and a projection laser joint surface LS with the thick part formed at inner side than the thin part in another side. The second member has a flat joint surface. By contacting joint surfaces of the first member and the second member each other, the laser L is irradiated to the first thick part and the thin part in a side of a laser irradiation surface of the first member and the thin part in a side of joint surface is deposited in the second member.SELECTED DRAWING: Figure 16 【課題】所定の吸光度の材料を使用しなくても部材同士の接合強度を確保し、外観品質を良好にできる溶着部品の溶着方法、当該方法に用いられる樹脂部品および溶着部品の溶着装置を提供する。【解決手段】本発明に係る溶着方法は、第１部材２１０と第２部材２２０を準備する。第１部材は肉厚が異なる第１厚肉部２１１と薄肉部２１２を備え、一方の側に平坦な接合面ＪＳを備え、他方の側に厚肉部を薄肉部よりも内方に形成した凸状のレーザー接合面ＬＳを設けている。第２部材は平坦な接合面を備える。そして、第１部材と第２部材の接合面同士を互いに接触させ、第１部材のレーザー照射面の側においてレーザーＬを第１厚肉部と薄肉部に照射し、接合面の側において薄肉部を第２部材に溶着する。【選択図】図１６
