Explain thermite welding |
|
Answer» Thermite welding is a process in which iron oxide reacts with aluminium and forms aluminum oxide and iron.this process is known as thermite welding process............. Fe2O3+2Al---------->Al2O3+2Fe+heat,this Fe is used to weld the broken railway sleepers . \xa0When iron oxide reacts with the aluminium lots of energy with molten iron is formed which is used in welding process. This process is called thermite welding.Fe₂O₃ (s) + Al (s) → Al₂O₃ + 2 Fe(l) + Heat |
