FIELD: metallurgy.
SUBSTANCE: metal plates are pressed by electrodes and conduct preliminary current pulse between them. For these plates welding electrodes with work part in form of cone with top angle from 100° to 140° are used. By means of the specified work part the electrode penetration to the metal plate surface and electric contact between electrodes and metal plates are ensured. After conduction of the preliminary current pulse the pressing force is increased and main current pulse is conducted.
EFFECT: invention ensures high quality welded joints by method of contact spot welding of metal plates with one-side non-conducting coating.
