FurseWELD Exothermic Welding

FurseWELD exothermic welding is a cost-efficient method of making large or small numbers of high quality electrical connections.

It is a simple, self-contained system that uses the high temperature reaction of powdered copper oxide and aluminium, within a mould, to form permanent electrical connections. Not only is this cost-effective, but also means FurseWELD can be used safely with minimum training.

The other main benefits of the FurseWELD system are that it is completely portable and requires no external power or heat source. With over 45 connection configurations available as standard, FurseWELD is a secure way of quickly creating highly conductive connections that are tolerant to repeated fault currents.

Exothermic welding using moulds for safe and robust electrical connections

FurseWELD graphite moulds are extremely robust and capable of producing up to 75 connections each, if not more when properly maintained. The range of FurseWELD moulds is designed to work with all common conductor formats - flat tape, stranded and solid circular.

Once created, most FurseWELD connections have at least twice the cross-sectional area of the conductors being joined, and an equivalent or greater current carrying capacity. Corrosion resistance is also exceptional due to the very high copper content (> 90%) of the alloy.

This gives FurseWELD many typical applications including:

  • Earthing for power plants and substations
  • Telecommunications
  • Transmission and power distribution lines
  • Cathodic protection
  • Rail connections
