Gouging carbon rod
A gouging carbon rod using an aluminum or aluminum alloy material as its conducting material includes a carbon rod unit, which has an elongated hollow main body internally defining a central space portion and having a first and a second open end; an aluminum/aluminum alloy unit, which is formed by high-pressure injection molding a molten aluminum or aluminum alloy material in the central space portion of the main body via the second open end, such that the aluminum/aluminum alloy unit so formed includes a shielded section located in the central space portion and an exposed section projected from the main body via the second open end. In this manner, the energy, time and labor costs for binding the aluminum material to the carbon rod are lowered, compared to the conventional carbon rod produced by metal thermal spraying technique, and the problem of uneven thickness of metal coating is solved..
