Will argon gas help to weld mild steel?

Argon gas is often used in welding mild steels. It is an inert gas, meaning it does not react with the molten steel, which helps to prevent oxidation and other impurities in the weld. Argon also helps to create a stable arc and provides good penetration. However, it is important to note that argon is not always the best choice for welding mild steels. In some cases, a mixture of argon and oxygen or carbon dioxide may be used to achieve better results.
