The types of auxiliary gases in laser processing are as follows

The types of auxiliary gases in laser processing are as follows:

1, inert gas, inert gas is also called rare gas (less used) or rare gas (less used), and they are all gases with single atom as molecule at room temperature.

2, active gas, active gas is very easy to chemical reaction gas, such as oxygen, hydrogen. At high temperature, gases that can react chemically with metals or dissolve in liquid metals are called active gases.

3. Inert gases such as helium, neon, argon, krypton, xenon and nitrogen are called inert gases. Also called conservative gas.
