    摘要： Methods are disclosed for gas shielded arc welding steel railroad rails spaced from each other to define a transverse gap, one of which methods comprises the steps of providing an elongated steel barrier plate wedged into the gap at the bottom of the spaced rails and filling gap above said steel barrier plate with a molten steel from an advancing filler metal electrode by a gas shielded electric arc welding process initiated by an arc between the electrode and the barrier plate. A second method comprises the continuous sequential laying of weld beads in the gap between rail heads along paths extending in laterally opposite directions for the beads to have first ends extending outwardly of an edge of the head in cantilever relationship thereto and which first ends are vertically thicker than second ends of the beads which are spaced from the first ends in the direction toward the opposite edge of the head.

    摘要： A welding unit for connecting two rails of a track by flash-butt welding, includes clamping jaws having contact surfaces intended for application to a rail web and a power jaw for current transmission having a contact surface for application to the rail web. The power jaw is displaceable relative to the clamping jaw in a pressing direction leading to contact with the rail. In an inoperative position spaced from the rail web, the power jaw, due to the pressure of a pressure spring, is situated in a forward end position with regard to the pressing direction, in which the contact surface of the power jaw projects beyond the contact surface of the clamping jaw.
