Our product range contains a wide range of Thermit Welding Equipments
Also known as exothermic welding, and thermit welding, is a welding that employs molten metal to permanently join the conductors. The process employs an exothermic reaction of a thermite composition to heat the metal, and requires no external source of heat or current. The chemical reaction that produces the heat is an aluminothermic reaction between aluminium powder and a metal oxide.
In exothermic welding, aluminium dust reduces the oxide of another metal, most commonly iron oxide, because aluminium is highly reactive. 3 C u 2 O + 2 A l 6 C u + A l 2 O 3 displaystyle mathrm 3 Cu_2O+2Allongrightarrow 6 Cu+Al_2O_3 Thermite welding is widely used to weld railway rails. Thermite welding is also use to making electrical connections to steel and ductile iron pipelines as well as other metallic structures, which are to be cathodically protected or electrically earthed.
