A fixing element has a base area that is provided for the purpose of being welded to a component, and a functional head protruding from a base area that is formed by at least one spherical, or sphere-like element. The fixing element may be welded to a first component and function as a male fixing element that cooperates with a female fixing element of a second component such that the first and second components are detachably connectable via the fixing elements.

A stud welding process and a stud welding device for welding a stud to a workpiece are provided, wherein an arc (LB) is generated between the surface of the stud that faces the workpiece and the workpiece by using a pulsed welding current (Is), and the arc (LB) is deflected by a magnetic field which is generated by a coil through which a current (I.sub.A) flows. The current (I.sub.A) through the coil for generating the magnetic field for deflecting the arc (LB) is activated synchronously and in anti-phase with the welding current (I.sub.s) by a current (I.sub.A) always being applied to the coil when the welding current (I.sub.s) is at a minimum, and the coil being switched off or the current (I.sub.A) through the coil being reduced to a minimum when the welding current (I.sub.s) is at a maximum.

A repair pin-stud used in processes for repairing panels, such as honeycomb panels. The repair pin-stud includes a cylindrical stud member, a tip on a first end of the cylindrical stud member, and an elongated installation member connected to a second end of the cylindrical stud member. The repair pin-stud further includes a tubular pin concentric with the cylindrical stud member. A first end of the tubular pin is connected to the cylindrical stud member, and a second end of the tubular pin is open and the elongated installation member extends outwardly from the second end of the tubular pin.

A stud feed assembly for welding studs comprising a stud loader and a stud catcher. The stud loader comprises a first chute component and a second chute component, the first chute component having a greater diameter than the second chute component. The stud catcher comprises a receiving component and a vertical component, the receiving component being shaped to receive it stud such that the receiving component aligns the received stud in a substantially vertical position.

A method for carrying out a stud joining process by a tool performing a working step on a workpiece and the working step is carried out while taking into account at least one parameter value which is selected from a set of values, and the working step is to be carried out at a certain position on the workpiece, and the position determines the parameter value. The method comprises the steps of: storing the parameter value for the position in an RFID transponder; locating the RFID transponder on the workpiece in the region of the position before the working step is carried out, reading the parameter value out from the RFID transponder with an RFID communication device associated with the tool.

A weld stud for drawn-arc stud welding has a functional portion and a welding portion which represents one end of the weld stud and which is delimited by a front face that is curved outwards in a longitudinal direction of the weld stud.

A device and a method for position measurement for welding guns, wherein based on the inductance of the coil, which changes depending on the insertion depth of the welding stud into a solenoid coil, it is inferred how far the welding stud is inserted into the solenoid in order to allow conclusions to be drawn concerning a proper arrangement of the welding stud relative to the workpiece.
