FIELD: metallurgy.
SUBSTANCE: sheets are welded by means of a pair of welding electrodes connected to a power supply for spot welding using a direct current inverter current. At first multiple repetitions of current transmission and stops of current transmission are performed at compression of steel sheets by welding electrodes with formation of a weld point. After the pulse process, a continuous current transmission is carried out for longer period of time, then maximum time of the current transmission in the pulse process when the steel sheets are compressed by the welding electrodes. Steel sheets are welded. During continuous current transmission, maximum current value is set below maximum current value in pulse process.
EFFECT: method makes it possible to obtain weld joints of high quality with use of wide range of inverter direct current.
