Beschreibung
Zusammenfassung:	FIELD: machine engineering, possibly processes of installation and restoration of aggregates including rotor machines. ^ SUBSTANCE: method comprises steps of opening technological holes in stator of rotor machine before performing welding operations in constructions joined with rotor machine; introducing into said holes electrically conducting pins having developed contact surface until achieving their contact with electric current conducting surface of rotor; performing welding operations and removing pins; closing holes. ^ EFFECT: reliable protection of bearing assemblies of rotor machines against electric current at performing welding operation in aggregate. ^ 2 dwg
