PROGRAM CONTROL DEVICE FOR CONTROLLING FLASH BUTT WELDING PROCESS

摘要

Abstract of the DisclosureA device of the invention comprises weldingcurrent pick-ups switched into each welding circuit.Outputs of the said welding current pick-ups are conn-ected to a logical coincidence means generating itsoutput signal provided so that to all its inputs areapplied signals. The said output signal starts awelding program control means controlling a driveadapted for moving the workpieces being welded. Theproposed device permits a flashing allowance of theworkpieces being welded to be decreased, and the effic-iency of the process and the quality of the resultingweld joints to be improved.
