Provided are a vehicle body assembling method and a vehicle body assembling apparatus which allow a simple configuration in the vicinity of the connecting portion between an upper jig and a lower jig and allow an increase in the efficiency of assembling work (welding work). A vehicle body assembling apparatus is equipped with a jig for supporting vehicle body components in a preassembled position, the jig comprising an upper jig and a lower jig which are connected to each other in at least two places. Each of the connection places is provided with a connecting means for fixing a three-dimensional coordinate position while allowing uniaxial turning. The vehicle body assembling apparatus is also equipped with a conveying means for conveying the upper jig which supports the vehicle body components, and reduces the load applied to the lower jig from the upper jig when connecting the upper jig to the lower jig.

An apparatus of a setting welding device for an auxiliary joining part with a head and a shaft, includes a linear drive fastenable at the setting device and including an element nest at a movable end, in which an auxiliary joining part is releasably receivable from a transfer unit. The element nest is movable by the linear drive in a first direction. The element nest is supported in a floating manner, and is positionable via a mechanical stop alignment in abutment with an electrode punch in the joining direction below the electrode punch. And/or the element nest is connected with the linear drive via a mechanical direction-changing coupling component so that the element nest is movable by the linear drive in a second direction so that the auxiliary joining part is positionable at the joining location, wherein the second direction is not parallel to the first direction.

A resistance welding device, comprising a frame for supporting a tool configured like a clamp with two arms arranged facing one another and having respective welding electrodes, of which a first arm is integral to the clamp and the second arm is assembled with the capacity of being moved with respect to the clamp by means of a first actuator, such that respective movements along a straight trajectory can be imparted to the arms of the clamp for moving their electrodes closer to or away from one another.
