No, not all noble gases have at least 3 electron shielding layers. The noble gas helium (He) has only two electron shielding layers, while the remaining noble gases (Neon, Argon, Krypton, Xenon, and Radon) have three or more electron shielding layers.
No. Not sure what you mean by a shielding layer- I would take this as the filled electron shells below the "outer", highest energy layer-- He has none, Neon has one , Argon has two.

Yes, helium, neon, argon, krypton, xenon, and radon are all classified as noble gases. These gases are characterized by their low reactivity, full outer electron shells, and stable configurations. They are primarily used in various applications such as lighting, lasers, and shielding.
Nonreactive gases (or noble gases) are often used as a shielding gas to prevent atmospheric contamination, or as an insulator in high voltage circuitry. They are also often used to modulate wave frequencies for anything from light to radar to X-rays.

Shielding gases in welding protect the molten metal from reacting with the surrounding air, which can lead to defects like porosity and oxidation. They also help stabilize the arc and improve the quality of the weld by controlling the heat input and transfer.
Noble gases have 8 electron shielding layers. This is because noble gases have a full outer electron shell, so they have filled all available energy levels up to the 8th shell, leading to 8 electron shielding layers.
This is a chemical element. You can find the how many electron in a single atom by using a periodic table.
CO2 is an oxygen compound or a non-inert gas,the purpose of a shielding gas is to shield the weld and the electrode from oxygen. argon, nitrogen and helium are the most common gases used for GTAW

There are many gases. Major reason is industrial gases.
Typically, elements with higher atomic numbers have better shielding due to more inner electron shells that shield the outer electrons from the positive charge of the nucleus. For example, noble gases like xenon or radon would have better shielding compared to elements with lower atomic numbers like lithium or carbon.
Inert Gases

There are many gases. Major reason is industrial gases.
These inert gases are used in gas tungsten arc welding, and also in gas metal arc welding for the welding of non-ferrous metals. Semi-inert shielding gases, or activeshield gases, include carbon dioxide, oxygen, nitrogen, and hydrogen. These active gases are used with GMAW on ferrous metals.
