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.

Apparatus and method for forming electrical connections

A mold assembly and method for lap welding a conductor to a vertical bar or rod features two vertically split mold parts having a major parting surface in which are formed a crucible, tap hole, sleeving for the conductor and a weld chamber. An offset parting surface forms a sleeving passage for the vertical bar or rod, and a portion of the weld chamber. The offset parting surface is formed in an interfitting tongue and groove which assists in the assembly of the mold parts.
