Abstract: Exothermic welding molds, weld-metal containing cartridges for such molds, and methods of use are provided. The mold, cartridges, and methods can provide interaction between the cartridge's disk member with the mold, which allows the housing member to be withdrawn from the mold while leaving the disk member and weld-metal in place. The interaction can be a rotational restraint alone, a vertical restraint alone, or combinations thereof. Alternately, the interaction can be an outward pressure on the housing member and/or disk member, a shear force on the housing member and/or disk member, or combinations thereof. The outward pressure on the housing member and/or disk member can alternately be provided without interaction between the disk member and the mold, but rather by the simple application of an internal pressure to the cartridge. The internal pressure can be applied by squeezing the walls of the cartridge and/or by depressing a pusher member.
