In order to further improve a method for joining a multilayer component (10) to another component (11) in a way that allows the multilayer component (10) to be mechanically and electrically joined to other elements, it is provided that an intermediate layer (14) of the multilayer component (10) be displaced in the region of the joining site (32), and that the two outer structural elements (12, 13) of the multilayer component be joined to one another by applying an electric voltage; and that the other component (11) be joined as a fastening element to the multilayer component (10) in the region of the joining site (32).
摘要:
Joining apparatus for joining joining elements onto workpieces, comprising a joining element holding device, which is configured to radially hold a joining element, and comprising a loading pin arrangement, which is configured to slide a joining element axially into a holding position in the joining element holding device, and/or to axially support the joining element during a joining process, wherein the loading pin arrangement has a loading pin, which is slidable by means of a loading pin actuator arrangement in the direction of the joining element holding device. The loading pin arrangement is here designed to variably establish a loading pin stroke of the loading pin between at least two stages, so that in a first stage the loading pin is displaceable less far in the direction of the joining element holding device than in a second stage.
摘要:
A welding apparatus for joining a weldable fastening element onto a workpiece by a welding process, wherein the welding apparatus comprises: an electric welding power source; a fastening element holding device for holding the fastening element during welding; a first drive device for moving the fastening element holding device along a first axis; a cleaning electrode holding device for holding a cleaning electrode along a second axis; and wherein the cleaning electrode is connectable to the electric welding power source. The fastening element holding device and the cleaning electrode holding device are mounted on a common tool carrier and the tool carrier is movable on a joining head by a tool carrier drive from a joining position to a cleaning position, and in the joining position the first axis defines a joining axis, and in the cleaning position the second axis is aligned with the joining axis.

The method also includes removing material from the blank to form a finished part, wherein the plurality of studs remain attached to the blank during removing. The method also includes detaching the plurality of studs from the finished part.
摘要:
A drawn arc welding process that includes the steps of providing a work piece, providing a welding tool holding a metal object onto the work piece, providing a power supply outputting a preset current, providing an arc voltage sensing device, lifting the metal object and drawing a pilot arc current, energizing a welding current locally melting the metal object and forming a weld pool in the work piece, measuring an arc voltage, predicting the arc voltage for a remaining time of the welding process, regulating the time of the welding process wherein the measured arc voltage and predicted arc voltage are utilized to control a desired energy input set point, and plunging the fastener into the locally melted work piece forming a weld between the metal object and the work piece.
摘要:
A hydraulic port weld stud that includes a stud portion having a longitudinal axis and a first bore formed along the longitudinal axis less than an entire length of the stud portion. A port portion extends along an axis transverse to the longitudinal axis of the stud portion. The port portion includes a second bore extending along the transverse axis and intersects the first bore of the stud portion. The port portion and stud portion are integrally formed without the need for a joining or welding operation.
摘要:
A welding head for a welding device is operable to weld a component which is not rotationally symmetrical onto a workpiece. A head attachment includes a holding device for holding the component and to carry a welding current to the component. A mouthpiece is arranged around the holding device and the component during a welding operation. The holding device and the mouthpiece move in relation to each other along a welding axis. The mouthpiece contacts the workpiece and provides a protective gas tangentially about the welding component. An interface device supplies the welding current to the holding device. A connecting device mechanically connects the holding device to the interface device. The connecting device is subdivided into a first connection piece connected to the holding device and a second connection piece electrically insulated from the first connection piece.
