The gaseous mixture used for welding of metals is
Show Hint
Oxy-acetylene welding uses C$_2$H$_2$ and O$_2$ to create a flame hot enough to melt metals, making it one of the most common welding techniques.

- C$_2$H$_4$, O$_2$
- C$_2$H$_{10}$, O$_2$
- C$_2$H$_2$, N$_2$
- C$_2$H$_2$, O$_2$

Verified By Collegedunia
The Correct Option is D
Solution and Explanation
The gaseous mixture commonly used for welding metals is acetylene (C$_2$H$_2$) and oxygen (O$_2$). This mixture is used in oxy-acetylene welding, where acetylene burns in the presence of oxygen to produce a high-temperature flame (around 3,500°C), which is sufficient to melt and join metals. Among the options, C$_2$H$_4$ (ethylene) and C$_2$H$_{10}$ (butane) are not typically used for welding, and N$_2$ (nitrogen) is not a suitable gas for creating the necessary flame.
Thus, the correct answer is C$_2$H$_2$, O$_2$.
