摘要： A device and a method for welding a welding stud to a substrate are disclosed. A welding current is applied to a welding stud between the welding stud and the substrate, whereby a material of the welding stud and the substrate is partially liquefied. The welding stud is then immersed into the solidifying material of the welding stud or the substrate in order to create a bond between the welding stud and the substrate.

摘要： Provided are a stud supply device and a stud supply method with which a stud can be supplied to a welding electrode in the correct orientation. The stud supply device comprises: a magazine in which a predetermined number of studs can be aligned and stored in series inside a magazine hole from a stop part to one end side; switching mechanisms having a plurality of balls that can move between a position contacting the studs and a position not contacting the studs, and a reciprocating member that restricts the movement of the plurality of balls, the switching mechanisms switching between a state in which the studs are stopped at the stop part and a state in which the studs are allowed to pass; and a first air injection part that is provided more on the one end side than the stop part, and that injects air from the one end side to the stud stopped at the stop part.

摘要： A component filling device and a component filling method are provided which, with a configuration that does not involve contact with the workpiece during a stud gun welding operation, can fill a component supply device with a prescribed number of components from a component feeding device. The component filling device (a stud filling device) is provided with: a component storage unit (a tube) which, inside of a component storage hole (the tube hole), can store a prescribed number of components (studs) aligned from a stopping unit towards the top; and a switching mechanism which comprises multiple moving bodies (balls), which can move between a position contacting a component and a position not contacting the component, and a lock unit (a rotation member), which restricts the moving bodies from moving, wherein the switching mechanism can switch between a state in which the stopping unit stops the components and a state in which the components are allowed to pass.

摘要： A welding element is operable for being connected to a workpiece using a welding method. The welding element comprises: a head and a shaft like anchor portion. The head includes a welding surface, a stop surface that is remote from the welding surface, and a plurality of pointed projections evenly and uniformly distributed over the entire welding surface. The shaft-like anchor portion extends along a longitudinal axis between a first end region and a second end region, with the first end region connected to the stop surface.

摘要： 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.
