ABSTRACT:
A method of, and apparatus for, respectively controlling the start of welding and the termination of welding during continuous resistance welding with the aid of an alternating-current at a roll-welding machine, wherein at least at one measuring station or location arranged ahead or upstream of the welding station or location and the workpiece to be welded passing through the measuring station there is determined the position as a function of time of the leading end as well as the trailing end of the workpiece to be welded with respect to the frequency and the phase of the welding current. By means of a computer processing the determined value there is accommodated to one another the speed of the workpiece to be welded and the frequency and phase of the welding current in such a manner that the first welding spot and the last welding spot are applied at an adjustable spacing from the leading end and the trailing end, respectively, of the workpiece to be welded.
