Thermit welding uses the following energy source ?
Correct answer: B. Chemical energy
- A. Electrical energy
- B. Chemical energy
- C. Energy of high velocity electrons
- D. Heat generated by friction
Explanation
Thermit welding uses an exothermic chemical reaction, usually aluminium reducing a metal oxide, to produce molten metal and intense heat. Thus its energy source is chemical rather than electrical or frictional.
