FIELD: machine building.
SUBSTANCE: method comprises inductance coil 7 introduction into can metal housing 1, through which alternating current is passed for flange 4 heating. Then coil 7 is removed from can 1, and flange 4 is overlapped with laminated cover. Heating system for method implementation comprises induction coil and coil power supply unit.
EFFECT: group of inventions ensures higher leak-tightness.
