<p>An arc welding automat for maintaining or repairing rails and switch gears includes a frame, a welding device including a torch for welding an area of a rail, the frame being provided with at least two elements for the support on a rail or a switch gear, these two elements and the torch being substantially aligned, the torch including an element of displacement on at least two horizontal axes. The automat includes an element for performing steps of:-storing, in a reference system having at least two dimensions, space coordinates of points forming at least two polygons defining at least two distinct working surfaces inside an area to be welded;-implementing a welding program including moving the torch with respect to the frame, so as to intervene successively on all the distinct working surfaces. Also disclosed is a welding method for maintaining or repairing rails and switch gears.</p> |
