Abstract
A device and method for welding a welding stud to a base is provided. A welding current is applied to a welding stud between the welding stud and the base material, wherein a material of the welding stud and the base material is partially liquefied. The welding stud is then immersed into the solidifying material of the welding stud or the base material in order to create a bond between the welding stud and the base material.
Claims20
A device for welding a welding stud to a base material, the device comprising a stud holder;
- a welding-current contact element for applying a welding current to the welding stud to partially liquefy a material of the welding stud and/or the base material;
- a stud immersing device for immersing the welding stud into the liquefied material of the welding stud and/or the base material when the welding stud and/or the base material is partially liquefied due to the welding current;
- a detecting device for detecting one or more parameters of a welding operation;
- a data memory for storing the one or more parameters detected by the detecting device;
- and a control device which is suitable for comparing the one or more parameters detected by the detecting device during a current welding operation with the one or more parameters stored in the data memory.
