What are the benefits of adding hydrogen to argon for welding?
The benefits of adding hydrogen to argon for welding.
The hydrogen is not used as primary shielding gas because hydrogen is not an inert gas. The hydrogen is added with the argon and then it is used.
The primary shielding gases that are used in the welding are argon (Ar) and helium (He). The argon (Ar) and helium (He) are inert gases that are used shielding.
Whenever in the welding operation there is deeper penetration and higher welding speeds are required, the hydrogen is added with the argon and then it is used...
