EXOTHERMIC WELDING, الطاردة للحرارة اللحام

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 Furse Weld 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.

Good video - it has really helped in explaining this concept (as well as increasing ground area) to my students! Thanks!
