STUD WELDING PROCESS AND STUD WELDING DEVICE FOR WELDING A STUD TO A WORKPIECE

摘要

The invention relates to a stud welding process and a stud welding device (1) for welding a stud (6) to a workpiece (2), wherein an arc (LB) is generated between the surface (7) of the stud (6) that faces the workpiece (2) and the workpiece (2) by using a pulsed welding current (I_S), and the arc (LB) is deflected by means of a magnetic field which is generated by a coil (3) through which a current (I_A) flows. According to the invention, the current (I_A) through the coil (3) for generating the magnetic field for deflecting the arc (LB) is activated synchronously and in anti-phase with the welding current (I_S) by a current (I_A) always being applied to the coil (3) when the welding current (I_S) is at a minimum, and the coil (3) being switched off or the current (I_A) through the coil (3) being reduced to a minimum when the welding current (I_S) is at a maximum.
