FIELD: machine engineering, instrument making, namely apparatuses and processes for single-side contact spot welding.
SUBSTANCE: method comprises steps of compressing welded parts by means of electrodes; at side of upper part approaching inductor connected to source of controlled e. m. f.; simultaneously passing through welded parts and inductor AC directed to one side at zero phase difference.
EFFECT: enhanced quality of welded joint due to lowered value of by-passing electric current and improved fusion of lower part.
