摘要

Procedure for obtaining and isolating welded joints in the front joints of the stator windings of large alternators, using insulating caps in the form of a cup, making up the insulating cap of heat resistant material and keeping it in a horizontal position from its open side it is pushed on the bar ends directed downwards, and the content of the cap is heated by induction heating whereby the welding material and the flux introduced from above into the insulating cap melt producing low welding simultaneous total filling of the free gaps still existing between the copper conductors and the cap and so that the insulating cap is maintained as partial insulation on the welded joint, characterized in that the insulating cap is composed of a shrinkable material, resistant to heat, and that is emphasized on the ends of the bars.
