FIELD: electricity.
SUBSTANCE: metal wire or tape is welded using roller electrodes with pulsed welding current. On two sides of each roller electrode through insulators, additional electrodes are fitted which encircle the roller electrode, and between which, simultaneously with welding current pulses, current pulses are passed for heating the welded wire or tape and the surface of the component in their contact zone. The roller electrodes for welding the wire or tape are connected to one welding transformer and the additional encircling roller electrodes are connected to another welding transformer.
EFFECT: additional heating of the contact zone between the metal tape and the component using rollers increases bonding strength of the metal tape with the component.
