A device comprises a frame, a plurality of fingers, and an integrated slide hammer to drive a coupler onto a first pipe. The device may drive the coupler backwards onto a second pipe. The device may position the coupler for fusion without having to remove the device for the backward driving of the coupler. The device may be used above ground or in a trench.

PROCESS AND APPARATUS FOR RAIL RESTORATION AND RAIL MANUFACTURE USING WELDING
A method for restoring a worn rail section includes cleaning a worn surface of a rail section to expose a clean metal surface, heating the rail section to a first temperature before welding, welding new metal on the clean metal surface of the rail section after heating the rail section to the first temperature, heating the rail section to a second temperature after the welding to heat-treat a heat-affected area caused by the welding, and shaping the rail section, wherein the welding is performed by a gas metal arc welding
E01B 31/18 - Reconditioning or repairing worn or damaged parts on the spot, e.g. applying inlays, building-up rails by weldingHeating or cooling of parts on the spot, e.g. for reducing joint gaps, for hardening rails
E01B 29/42 - Undetachably joining or fastening track components in or on the track, e.g. by welding, by gluingPre-assembling track components by gluingSealing joints with filling components
B23K 9/04 - Welding for other purposes than joining, e.g. built-up welding
