Aluminothermic welding is a method in which, due to the reaction caused by the copper oxide reduction by aluminum, a durable two metal element (copper-copper or copper-steel) bond two metal elements (copper-copper or copper-steel) is obtained.

The reaction takes place in a graphite mold in which the elements to be welded have previously been introduced and at the required load. This results in a durable, compact and homogeneous bonding between the elements.

The conductivity of the welding connection is equal to or greater than two joined conductors.

The connection is resistant to overloads or surges.
