The design and execution of an earthing system is a fundamental step in any type of construction. A good state of an electrical facility is vital for any modern facility, whether industrial or civil, due to the large number of processes carried out by elements connected to it. The connection of metallic elements of an earthing system can be carried out mechanically or by welding (such exothermic welding), although not all of these types of connection ensure reliable and, above all, long-lasting connections.
Galvanic corrosion occurs between two metals with different oxidation potentials, such as steel and copper. However, other conditions are also required, thanks to which Apliweld® Secure+ aluminothermic welding does not oxidise the corrugated steel to copper cable connection.

Exothermic welding, also known as aluminothermic welding, is the result of a process that achieves the molecular union of two or more metallic conductors through a chemical reaction. If it is performed correctly, it results in a bond that is superior in conductivity and durability to any that is carried out mechanically. To obtain this, it is vital to follow certain criteria that determine the quality of the welding.
