PROGRAM CONTROL DEVICE FOR CONTROLLING FLASH BUTT WELDING PROCESS

A device of the invention comprises welding current pick-ups switched into each welding circuit. Outputs of the said welding current pick-ups are connected to a logical coincidence means generating its output signal provided so that to all its inputs are applied signals. The said output signal start...

Beschreibung
Zusammenfassung:	A device of the invention comprises welding current pick-ups switched into each welding circuit. Outputs of the said welding current pick-ups are connected to a logical coincidence means generating its output signal provided so that to all its inputs are applied signals. The said output signal starts a welding program control means controlling a drive adapted for moving the workpieces being welded. The proposed device permits a flashing allowance of the workpieces being welded to be decreased, and the efficiency of the process and the quality of the resulting weld joints to be improved.
