PROBLEM TO BE SOLVED: To provide a work joining method capable of suppressing the equipment cost to be low at each production base when a small-lot production of cars is performed in many production bases. SOLUTION: The work joining method comprises an assembly step of assembling works A-G in a predetermined assembly state at one production base when performing a small-lot production at overseas production bases or the like, a temporary fitting step of temporarily fitting works assembled to each other in a predetermined assembly state in the assembly step by the spot welding, a work separating step of separating the works by releasing the joining by the spot welding while opening assembly holes in a spot welded part S formed in the temporary fitting step, and a permanently joining step of permanently joining the works with each other by positioning the works in a predetermined assembly state by transporting each work to each production base in this state, and utilizing the assembly holes at each production base. An assembly tool can be omitted or simplified at each production base, and the equipment cost can be suppressed to be low. COPYRIGHT: (C)2006,JPO&NCIPI
