What does inert mean in welding?

When discussing welding processes, the term “ inert refers to the properties of the gas used to fuel the welding process. This gas is referred to as “inert” because it does not react chemically with the metal being welded.

What is an inert welding process?

Today most welding processes use inert gas. This gas, which is sometimes referred to as shielding gas, is blown through the welding arc to help protect the molten metal from the air, which could cause oxidation. Inert gas is created when oxygen is removed from air, which is why it is called an “inert” gas.

What does the word inert mean in welding?

The word “inert” refers to the property of a molten metal to not react with the environment. This means that when molten metal is poured onto a pool of molten iron, the metal will not stick to the base metal but will rise to the top without any reaction. This can be achieved by adding a flux to the molten metal before pouring it. Fluxes are chemical compounds that alter the chemical composition of the molten metal, creating a molten metal that will not stick to the base

What does the word inert mean in arc welding?

The word inert means not chemically active. When discussing welding processes, inert refers to the purity of the gases that are used in the process. This purity depends on the type of gases used. For example, carbon dioxide (CO2) is considered inert when it’s used as a shielding gas in metal arc welding. However, CO2 is not inert when it’s used as a gas in cutting.

What does the word inert mean in the welding industry?

The term inert gas is used to describe a gas that is neither acidic, basic or flammable. It does not react with the surrounding environment or the materials it comes in contact with. When used in welding, an inert gas is used to shield molten metal from oxygen so as to prevent oxidation. It is also used to shield the molten metal from contact with air. The gas flow of an inert gas helps to create a clean, dry environment around the weldment.
