Exothermic Welding

Exothermic Welding

Exothermic welding is a simple, economical method of making permanent, very high quality electrical connections - the process uses the high temperature reaction of copper oxide and aluminium, within a semi-permanent grpahite mould, to form electrical connections mainly between copper to copper or copper to steel.

Exothermic welding requires no outside source of power or heat - the system is also light and portable ideal for field use. Making an exothermic welding joint is a simple procedure which requires a mould, weld powder, handle clamp and exothermic welding tools.

Exothermic welding, often called Cadwelding or FurseWELD, is a cost efficient method of making electrical connections - typical applications include earthing for power plants and substations, telecommunications, transmission and distribution lines, cathodic protection and rail electrification earthing.

Exothermic welding connections are tolerant to repeated fault currents, highly conductive, permanent and demonstrate excellent corrosion resistance - most exothermic welding connections have at least twice the cross-sectional area of the conductors being jointed.

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

The FurseWELD exothermic welding system requires no external power or heat source, creates high quality electrical connections, is completely portable, can be used safely with minimum training, is cost-effective and can be used for over 45 standard connection configurations. FurseWELD exothermic welding connections have several advantages in that they are tolerant to repeated faults, are highly conductive, do not loosen and have excellent corrosion resistance because of the very high copper content (>90%) of the alloy.

T&D UK can provide nationwide Certified Training to contractors looking to install Exothermic Welding systems.
