About Irani Cadeweld Thermite

Irani specializes in exothermic welding, offering durable graphite molds and reliable weld cartridges for strong, lasting connections.

CADWELD CONNECTIONS TO STEEL CONNECTIONS

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 produces a permanent, high-conductivity connection.

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. They can be handled and stored without danger and can be shipped with no special packaging or marking.

Two types of CADWELD weld metal are used for cathodic protection connections:

  • F-33 alloy is used for all connections of cable to cable and cable to steel or stainless steel pipe.
  • POWDER SHOT (GUN POWDER), NOT FOR ELECTRONIC TRIGGER 
  • XF-19 alloy is used for all connections to cast iron.
  • UPC: 30782856001073
