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.

How to achieve safe and efficient exothermic welding without electricity sources aluminothermic earthing

Earthing is a fundamental step in any electrical system installation. It is also essential for the proper functioning and safety of equipment and people, as it protects against potential differences that can be dangerous in both cases. The Apliweld Secure + exothermic welding system allows permanent and reliable connections to be made safely thanks to its electronic initiator, but there is not always a source of electricity nearby. To overcome this obstacle, Aplicaciones Tecnológicas offers an add-on to charge the electronic initiator from any vehicle.

Exothermic aluminothermic welding earthing frequent questions

Aluminothermic or exothermic welding is the chemical process that allows two or more conductors to be joined together in a durable manner. It is mainly used in earthing systems due to its reliability, resistance and a series of advantages over other types of joints. Knowing whether it is properly carried out, how to calculate the necessary material or how to guarantee the safety of people in the event of a chemical reaction are the main questions answered by Aplicaciones Tecnológicas.
