Harger Horizontal Molds for Cast Iron/Ductile Iron Pipe

Harger CIHD Connection Type Mold (Horizontal Cable to Horizontal Flat Cast Iron/Ductile Iron Surface, ON Surface)

The Exothermic Process is an effective and safe method of welding copper to copper or copper to steel for the purpose of producing permanent electrical connections.  Exothermically welded connections are produced from the energy and molten copper metal liberated from an exothermic reaction between powdered copper oxide and aluminum.  The exothermic reaction takes place at a theoretical temperature of 4600-degrees Fahrenheit and as a result, molten copper alloy is created and used to melt the conductors and cast the finished connection.

The exothermic reaction takes place in a semi-permanent graphite mold that will last 50 or more welds if properly maintained.  The process is simple and easy to implement providing an on-site means to make welded electrical connections without requiring external power, equipment or the special training usually required for brazing and welding.
