Abstract
The present invention concerns a welding mold for butt welding two metal parts by casting a molten filler metal in an imprint defined by a mold. At least one of the components of the mould includes a spacer member shaped and sized so that it can be engaged in a gap between the two parts only if the latter have a mutual separation at least equal to a specific mutual separation, so as to allow the mutual assembly of the components of the mold around the parts to be welded only on this condition. Applications include the welding of railway rails, concrete reinforcing rods and metal bars.
