Summary:A method of, and apparatus for, controlling the welding energy during electrical resistance welding of workpieces, by means of an electrode roll-resistance seam welding machine. The effective value of the welding current is controlled in response to an electrical control signal, at least a component of which is a welding current-correction signal substantially analogous to the welding speed in order to provide a substantially constant welding energy supplied to the workpieces at each section along the formed welding seem at any welding speed. Said welding current-correction signal is produced by means of a programmed control device which simultaneously delivers an electrical rotational speed-reference value signal for controlling and regulating the welding speed.
