1.What is argon-hydrogen mixture?

Argon-hydrogen mixed gas is a commonly used shielding gas, which is widely used in welding, cutting, thermal spraying and other industrial fields. The proportion of argon-hydrogen mixed gas has an important influence on the protection effect and welding quality.

2.Is hydrogen argon mixture flammable?

Hydrogen-argon mixed gas is non-flammable, because in hydrogen-argon mixed gas, hydrogen occupies 2%~~5% of the total volume, and is evenly mixed in 98%~~95% argon, that is, the hydrogen content It is an extremely small amount, which cannot reach the combustion range, not to mention that argon is an inert gas.

3.What other gases can be blended with argon?

H2、O2、CO、CO2、CH4、C2H2、C2H4、C2H6、C3H6、C3H8

4.Influence of Hydrogen in Argon Shielding Gas on Welding Stainless Steel？

Chlorine gas is an inert gas and does not chemically interact with the weld metal of stainless steel processing and welding. The gas density is about 40% higher than that of air. It is not easy to drift when used, so it is a relatively good protective gas. The thermal conductivity of chlorine gas is relatively low, and it is not easy to decompose and absorb heat at high temperature. When the arc burns in hydrogen, the heat loss is low, and the ionization heat is low. Therefore, the arc combustion stability of chlorine gas shielded welding is the best among various gas shielded coals. . Especially in the fusion arc welding, the welding wire metal is very easy to transition to a stable axial jet, and the spatter is also very low, so it is widely used in fusion welding.
