ABSTRACT:
A door for a motorcar is manufactured by a method in which a door inner member is assembled by combining accessory parts such as a sash to an inner panel, a beam is combined to the door inner member and thereafter the door inner member is assembled to an outer panel. The assembling step of the door inner member is divided into a tack-welding step for tack-welding the inner panel and the accessory parts on a welding jig and a reinforcing-welding step for reinforcing-welding the door inner member by welding robots. The beam is charged into a reinforcing-welding station to weld it to the door inner member by the welding robots. An apparatus has a tack-welding station having disposed therein a welding jig, a reinforcing-welding station having disposed therein welding robots, an assembling station having disposed therein an outer panel setting jig, a first transfer apparatus which is provided with a transfer jig, a second transfer apparatus which is provided with a transfer jig, a beam charging apparatus, and a beam setting jig.
