Aluminothermic welding mold and repair method
The present invention relates in particular to a mold (M) for aluminothermic welding of a metal rail (1), which comprises at least two essentially identical parts or shells (4) that are configured so as to be temporarily assembled opposite one another and on either side of said rail (1) in order to enclose the head (10), the web (11) and the foot (12) of this rail (1), each part or shell (4) having an upper opening (43) which opens onto an internal cavity (44) bounded by walls (45, 46, 48) configured to enclose the head (10), the web (11) and the foot (12) of said rail (1), characterized in that said internal cavity (44) comprises a compressible sealing coating (5) only against the walls (451, 46, 48) that are configured to enclose said web (11), foot (12) and the underside of the head (10), with the exception of the rest of the head (10) and the underside of the foot (12).
