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.

Element supply apparatus for a setting welding device, an element nest and a retrofit kit for the setting welding device as well as corresponding supply methods of a welding auxiliary joining part

Rail conveyor element which can be displaced on a rail system with intersecting rails, includes a base and a wheel-bearing cassette which supports the base and in which at least one wheel is accommodated to rest on a rail, the wheel-bearing cassette is rotatably mounted around a vertical axis relative to the base and the rail conveyor element includes a pressure ram with actuator which extends downward on or below the base and can be displaced between a raised unloaded position which coincides with the transport position of the rail conveyor and a lowered loaded position to unload the wheel-bearing cassette relative to the rail.

A bolt setting method and device for a nail-shaped bolt with a head and a shaft, ending in a tapered manner. The bolt setting method includes: joining the bolt into a component with a deforming stroke during which the bolt reaches a first joining speed of ≤4 m/s and the shaft completely penetrates the components with a portion of a maximum diameter with respect to a shaft length, without a bottom side of the head abutting the at least one component, and after the deforming stroke, driving the bolt into the at least one component until a head abutment of the bottom side of the head on the at least one component by at least one friction stroke with which a frictional connection between the shaft and the components is overcome and with which the bolt reaches a second joining speed that is smaller than the first joining speed.

A method for determining the quality of a joint fabricated in a plurality of metal sheets by a joining device and a control method. The joining device comprises a drive element, and a hold-down device The method may have the following steps: moving the drive element to move the punch and, via at least one first and one second spring, the hold-down device; recording of a force applied by the drive element with a first sensor and of a distance covered by the drive element with a second sensor during a movement of the drive element in a mating direction and opposite thereto as a force/displacement curve; and comparing a linear relief range in the recorded curve with a reference curve.
