CAD WELDING

Procedure

The cad weld connection is made by dumping a container of weldThe cad weld connection is made by dumping a container of weld metal copper oxide and aluminum) into a semi permanent graphite mold housing the conductor with a flint igniter. The exothermic reaction produces molten cavity and weld the conductor to pipes.
