Question

how thermite welding be done?​

Answer 1

Working principle. In thermit welding process, a thermite material which is a composition of a metal oxide, aluminium and fuel is used to achieve exothermic reaction. ... The density of the aluminium oxide slag is much less than the liquid iron, so it floats above the molten iron.


plz follow me....... ✌✌

Answer 2

Hello!!

______________________________________________________________A strongly exothermic (heat-generating) reaction occurs that via reduction and oxidation produces a white hot mass of molten iron and a slag of refractory aluminium oxide. Copper thermite, using copper oxide, is used for creating electric joints.________________________________________________________________________.
