The present disclosure relates to a method for controlling a spot welding arrangement, the method comprising the steps of moving a welding tip portion of the spot welding arrangement between a first and a second position by applying a force to the welding tip portion; determining a distance moved between the first and second positions; determining a type of welding yoke connected to the spot welding arrangement based on the determined distance and the applied force; and controlling settings of the spot welding arrangement based on the welding yoke connected to the spot welding arrangement.

A setting welding device is set forth for setting stud-like auxiliary joining parts in a plurality of layers of material and subjecting them to a mechanical-thermoforming process on a second layer of material and connecting them to said second layer by way of a welding operation. For this purpose, the punch is used to apply to the welding auxiliary joining part mechanical and thermal loads that follow prescribed characteristic force and current curves. Furthermore, a corresponding connecting method that can be realized with the aid of the setting welding device is also disclosed.

A method for undetachably introducing a guiding aid element into at least one joining location of at least one component is provided. The method includes the acts of: a) perforating the at least one component at the at least one joining location in a first press stroke of a tool press, wherein a preliminary hole is formed at the at least one joining location; b) inserting a joining aid element into the at least one preliminary hole; and c) pressing the at least one joining aid element with the at least one component in a subsequent press stroke or working step to form a material-bonding, form-fitting and/or force-fitting connection between the at least one component and the at least one joining aid element. A component and a composite component produced by such a method are also provided.

One aspect of the present invention provides a method for preventing spot welding crack of a galvanized steel plate, which can reduce crack occurring due molten zinc having a low melting point when a galvanized advanced high strength steel (AHSS) plate is spot-welded, and can thus improve welding strength and fatigue life.

A bonded body includes a first metal piece, a second metal piece, and a spacer. The first metal piece has a first surface and a protrusion protruding on the first surface. The second metal piece has a second surface, and the second surface of the second metal piece is bonded to the first surface of the first metal piece at the protrusion. The spacer has an electrically insulating property. The spacer is provided on the first surface of the first metal piece, and located between the first metal piece and the second metal piece. The first metal piece and the second metal piece are arranged to face each other such that a portion of the first surface of the first metal piece outside of the spacer is exposed from the second metal piece.

A method for the connection of components or component regions and a non-releasable connection produced in this manner. Two connection faces are partially welded to each other with an adhesive layer being incorporated between the two connection faces. The method including the following steps: arranging a welding base on a connection face, applying the adhesive layer to a connection face, moving the connection faces toward each other in such a manner that the welding base is applied against the other connection face, introducing welding current in the region of the applied welding base. A spacer is arranged between the connection faces before the connection faces are moved toward each other. The connection faces are spaced apart from each other in the region of the welding base by the extent that the welding base projects above the spacer.

A weld joint manufacturing method of the present disclosure includes performing current-passing through an aluminum-plated steel sheet provided with an aluminum plating layer while moving a pair of wheel electrodes relative to the aluminum-plated steel sheet by sandwiching the aluminum-plated steel sheet between the pair of wheel electrodes and rotating the pair of wheel electrodes in a circumferential direction; and welding a part of the aluminum-plated steel sheet, where the current-passing has been performed, and another steel sheet, in an overlapped state of the aluminum plating layer with the other steel sheet.
