Exothermic Welding System

Exothermic welding is an innovative new way to connect two metals together. LegrandWeld Exothermic System uses the high temperature reaction of copper oxide and aluminum inside a semi-permanent graphite mould, to form electrical connections (mainly between copper and copper or copper and

No outside source of power or heat is needed when using the exothermic system. It is light and completely portable, making it ideal for field use. Creating an exothermic joint is a simple procedure which requires a mould, welding powder, handle clamp and various tools and cleaning accessories.

Typical Applications include:
• Sub Stations and Power Plants
• T&D Distribution Lines
• Rail Connections
• Telecommunications
