Continuous rail section welding process, and mobile welding apparatus used therefor

Abstract From the Canadian patent

A process for the continuous welding of railway track sections (3) during installation in which a set of wagons, especially equipped for the purpose (5-5') and made up of one or more wagons (5, 5') with an extra-low load plane is introduced into the line of operation between the wagons (1) carrying the new track sections (3) and the new cross beams (2) and the operating machine installing said beams and sections. The operations aligning levelling and butting successive track sections (3) take place on said set of wagons (5-5') as does the welding of said sections, which involves the movement of welding machines (15-17) on a trolley (8) along the set of wagons (5-5'). The welding operations …
