INTRODUCTION

Thermo welding, also known as exothermic bonding,
thermite welding, and thermit welding, is a type of welding that uses molten metal to permanently unite conductors.
To heat the metal, an exothermic reaction of a thermite composition is used, and no external source of heat or
current is required. The heat is generated by an
aluminothermic reaction between aluminium powder and metal oxide.
Exothermic welds are particularly helpful for connecting incompatible metals. The procedure has the benefit of requiring no external heat source and operates by using a chemical exothermic reaction of a thermite composition (weld powder) to heat the conductors to the point where a low resistance, mechanically sound molecular bond is created once cooled.

ADVANTAGES

  • Thermo welding is a simple and fast process of joining similar or dissimilar metals.
  • This process is cheap, as no costly power supply is required.
  • This process can be used at the places where power supply is not available.

APPLICATION

  • Very thick and heavy plates welding
  • Joining rail roads, Pipes and Thick steel sections.
  • Heavy castings and Gears repairing.
  • Locomotive rails, Ship hulls etc.
  • Welding cables made of copper.
