ABSTRACT:
An assembly and method are disclosed for exothermic welding including a mold which is formed of a material which withstands exothermic welding temperatures, and includes a weld cavity therein for positioning at least two members which are to be exothermically welded together adjacent to each other, and an ignition cavity communicating with the first cavity. The members which are to be exothermically welded together are positioned adjacent to each other using the weld cavity, and a weld metal cartridge is positioned in the ignition cavity. The cartridge comprises a container having copper walls which define a chamber therein, and a particulate weld metal in the chamber. The tip of an electrical igniter is positioned into the chamber of the container and particulate weld material therein, the igniter is electrically fired while the container is in the ignition cavity of the mold to melt the particulate weld material, and the contents of the ignition cavity are passed after melting the particulate weld metal to the weld cavity to weld the members together.
