Abstract
A two part exothermic weld mold assembly is horizontally split through a weld cavity. The upper single mold port includes a crucible offset from the weld cavity. The tap hole from the crucible to the weld cavity includes a vertical section and a slanted or inclined section, the latter being a through-hole from the weld cavity to the exterior of the mold. The inclined through-hole serves to vent gasses during welding and also enables the tap hole and adjoining weld chamber more easily to be cleaned for reuse.
