Abstract
The invention relates to a welding process for drawn arc stud welding wherein after ignition of the main current electric arc, the latter's voltage (U) is measured and, depending upon the measured voltage, the current flow of the continued main current electric arc and/or the dipping movement of the parts which are to be welded together, is regulated or controlled.
Claims20
A welding process for drawn arc stud welding wherein:
- a) after ignition of a main current electric arc, a voltage (U) is measured and
- b) depending upon the measured voltage (U), at least one of the course of the current of the continued main current electric arc and the movement of parts which are to be welded, is regulated or controlled.
A device for drawn arc stud welding, with at least one stud welding head (5) connected to a current supply and control unit (19) and a measuring and control unit (29), which regulates or controls the welding current (I), wherein the measuring and control unit measures at least one of measured voltages (U) and a measured average voltage (U.sub.avg) after ignition of a main current electric arc, and based on at least one of the measured voltage (U) and measured average voltage (U.sub.avg) adjusts the continued main current electric arc.
A welding process for drawn arc stud welding wherein:
- a) after ignition of a main current electric arc, a voltage (U) and an average voltage (U.sub.avg) are measured and
- b) depending upon the measured voltage (U), at least one of the course of the current of the continued main current electric arc and the movement of parts which are to be welded, is regulated or controlled.
