ABSTRACT:
An aluminothermic welding device. The device, which is for the butt welding of two metal members such as railroad rails, comprises a mould and a crucible the respective upper and lower faces of which are so formed with mutually complementary respective depressions and/or reliefs as to enable the crucible to be placed on the mould in a position in which the discharge aperture of the crucible and the pouring bush of the mould are coaxial and turned downwards and upwards respectively. This ensures the correct positioning of the crucible in relation to the mould. The crucible can also be constructed in a form enabling it to be used once and from a material selected for this purpose and advantageously differing from the material used for the mould.
