Exothermic Welding for Railway Applications

Product overview

Aplicaciones Tecnológicas Exothermic Welding for Railway Applications include APLIWELD® exothermic welding for connections between cable and rail. Hammer Die and corresponding Rail Sleeve references available below.

In order to ensure the connection is secure and to prevent material leakages, it is advisable (when not compulsory) to make use of the hammer-die corresponding to the rail sleeve at the end of the conductor to be welded.

Apliweld® Secure+ Exothermic Welding

Apliweld® Secure+ Exothermic Welding is a process that achieves the molecular binding among two or more metallic conductors by a chemical reaction. This molecular binding improves mechanical, electrical and anti-corrosion properties compared with any mechanical connection.

Apliweld® Secure+ is the best way to make permanent, reliable and high conductivity connections for any installation requiring an earthing system.

The appropriate tools should be selected in order to carry out rail welding. Use the tables in the PDF attached to assign the proper mould, tablets and clamp required depending on where the welding is to be carried out (head-web-foot), the size of the conductor to be welded (35-50-95… mm2) and if it goes all the way through or has an end point.

However, it is also important to establish the rail profile given that each rail varies in size and perhaps the same mould could work in a certain part of the rail and conductor for one rail but not for another.
