RAIL CONTACT BUTT-SEAM WELDING MACHINE Russian patent published in 2009 - IPC B23K11/04 B23K11/25 B23K101/26

Abstract RU 2366550 C1

FIELD: process engineering.

SUBSTANCE: proposed machine comprises housing with rail clamping mechanism, flashing-off and settling mechanism incorporating two welding transformers and weld trimmer. It incorporates also hydraulic system and control unit with the process follow-up system. The rail clamping mechanism represents two tongs clamps fitted on common axle to allow on of them to displace along the rail. The electrohydraulic process follow-up system comprises indicator to record exact position of the housing movable part and generate control signal for welding process. Clamping mechanism hollow axle accommodates aforesaid indicator.

EFFECT: higher welding quality, higher welding rate.
