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.

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 method of joining a high entropy alloy is provided. The method of joining a high entropy alloy includes the steps of: arranging specimens made of a high entropy alloy to be in contact with each other; and diffusion joining the specimens made of the high entropy alloy by simultaneously applying a compressive stress and a current to a joint of the specimens within a range in which the high entropy alloy does not melt.

A welding electrode apparatus has a base member and a locking ring for clamping a consumable electrode tip to the electrode base. The base and the tip are predominantly made of copper, or a copper alloy. The base member has a first end that is threaded to fit a welding head that supplies electric current; and an electrically conductive second end to which the electrode tip is mounted. The second portion has an externally facing, axially extending cylindrical wall. A circumferential groove is formed in the wall. The locking ring has a quick-disconnect feature in the form of an array of spring-loaded detents that deflect to release the cylindrical wall of the first member, and that spring inwardly to seat in the circumferential groove.

The present invention relates to a device for blocking cooling water of a weld gun, the device preventing water leakage by blocking the cooling water leaking from the weld gun when a tip provided to the weld gun is replaced. The device for blocking the cooling water of the weld gun comprises: a first piston valve (23) connected to a first solenoid valve (17), operated by a signal of a control unit, so as to start operation according to a signal thereof, and receiving the cooling water from a cooling water inlet end; a main supply pipeline (23) of which one side is connected to a cooling water inlet pipe (27) of the weld gun and the other side is connected to an outlet end of the first piston valve (23); a second piston valve (29) operated by a first solenoid valve (15), and provided on a main discharge pipeline (31) so as to cut off the cooling water discharged or allow the same to pass therethrough; a suction means (35) for suctioning the cooling water filled in the pipeline by means of vacuum and holding the same when the weld gun tip is removed such that the pipeline is opened; and a pressure sensor (49) for sensing that the weld gun tip is separated and the pressure of the pipeline instantly drops so as to drive a circuit, thereby sensing an instant change in fluid pressure; and a cleaning means (47) for removing scales and foreign substances accumulated inside the weld gun, using spraying of air pressure.

A system and method to correct for height error during a robotic additive manufacturing process. One or both of an output current, output voltage, output power, output circuit impedance and a wire feed speed are sampled during an additive manufacturing process when creating a current layer. A plurality of instantaneous contact tip-to-work distances (CTWD's) are determined based on at least one or both of the output current, output voltage, output power, output circuit impedance and the wire feed speed. An average CTWD is determined based on the plurality of instantaneous CTWD's. A correction factor is generated, based on at least the average CTWD, which is used to compensate for any error in height of the current layer.
