FIELD: machine building.
SUBSTANCE: method includes heating by arc of section of pass from seam to main metal. It is implemented controlled-transfer heating by cycling for metal by base current Ib=20÷50 A and by pulse current Ip, value of which is selected from ratio: 
,
where τb - duration of bas current, s, τp - duration of current in pulse, s, k=(1.3÷3.5) - coefficient, defining tolerance of parametre correlation of cycle, and with current pulse frequency f=0.1-0.3 Hz.
EFFECT: effective reduction of welding temper, increasing of mechanical properties of welded joint metal.
