CADWELD connections are made with a semi-permanent graphite mold, which holds the conductors to be welded. Weld metal (a mixture of copper oxide and aluminum) is dumped into the top of the mold. The mold is covered and the weld metal ignited. The exothermic reaction produces molten copper, which results in a permanent, high conductivity connection. A CADWELD Connection has current carrying capacity equal to that of the conductor, is permanent with a low resistance connection that cannot loosen or corrode, uses lightweight, inexpensive equipment, requires no external source of power or heat, and can be easily checked for quality.
Cadweld Weld Metal Cadweld weld metal is a mixture of copper oxide and aluminum, packaged by size in plastic tubes. Each tube contains the starting powder at the bottom of the plastic tube, with the weld metal on top. These containers are packaged, with metal disks, in polyethylene boxes. The welding metal cannot ignite spontaneously.
Cadweld E-Z Change, 3" Handle Clamp Handle Clamps such as the one shown are required for most molds. Specialized frames with handles are used on some molds. Flint ignitors are included with all Handle Clamps.
