Weld Material

Weld metal, a mixture of copper oxide and aluminum, is packaged in individual, moisture resistant cartridges. Each cartridge contains a small amount of igniting material at the bottom, separated from the weld metal on top. These materials are not explosive and not subject to spontaneous ignition. One metal disk is typically included for each connection, but it is advisable to have extras available. Not all exothermic Exothermic Welding 2welds end up looking like this poster child photograph.

Based upon the proficiencies of your technicians, it is advisable to order at least 10% more weld material for the project so that your crew is not being held up while they wait for an overnight express package. Weld cartridges should be stored in a dry environment at all times.
