Conductive stud welding

The invention relates to a conductive stud welding, specifically to a method for welding the first workpiece and the joint component, wherein the joint component and first workpiece are both partly made of metal, the joint component rotates relative to the first workpiece in the welding process, and is simultaneously pressed on the first workpiece along the axial direction so as to form mechanical contact, wherein the friction heat is generated. The object of the invnetion is to provided a method for welding the joint component and the material, which can form a connection with firm bonding and dependable process between the joint component and the workpiece, when the workpiece is constituted by composite material or has low rigidity, the connection is realized by current generated between the workpiece and joint component during the mechanical contact of the joint component and the first workpiece. At least one current pulse is guided in at the same time when the joint component moves to the first workpiece.
