PURPOSE:To aim at reducing the number of steps of a vehicle assembly and as well at effectively utilizing a space, by rationalizing the order of the introduction of parts for a small size part set step, a large size part set step and a welding step. CONSTITUTION:A rear floor panel (a) is set on a carrier vehicle 22 from a storage yard 21 for rear floor panels (a) by means of a conveyer unit. While small size parts such as, for example, brackets (b) are set by means of a carrier vehicle 23, the panel (a) is introduced into a first welding device 24 by a conveying means N. Small size parts are introduced into the first welding device 24 after completion of setting thereof, and therefore the small size parts together with the panel (a) are subjected to multi-welding. The workpiece is introduced, after completion of the welding, into a second welding device 25 by a conveying means S. A rear member assembly which has previously assembled on an assemblying step 26 has been introduced in the second welding device 25 in which the panel (a) is welded to the rear member assembly. The welded workpiece is introduced into another welding device 27 in which the workpiece is welded to a bracket which is transferred by a carrier vehicle 28, to complete the assembly of the vehicle body. |
