Solution

Ferric oxide $({Fe}_{2} O_{3})$ reacts with metal X to produce heat which can be used for welding purposes.
Ferric oxide $({Fe}_{2} O_{3})$ undergoes reduction with the metal Aluminium to form thermite.
Reduction of Aluminium is also known as Alumino thermic process or thermite process.
The obtained Iron is in molten state and due to produced heat, it is used for joining railway tracks.
This implies that metal X is Aluminium.
The chemical reaction occurs as follows:
$\underset{(Ferric oxide)}{{Fe}_{2} O_{3} (s)} + 2 Al (s) \overset{heat}{\to} 2 Fe (s) + \underset{(Aluminium oxide)}{{Al}_{2} O_{3} (s)} + Heat$
