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.
