Mix gas welding: hydrogen - argon

Welding mix hydrogen - argon is used as the protective gas environment when welding austenitic by staly.

Argon allows to receive and keep a good and steady arch from beginning to end of welding because of its low ionization potential.

Hydrogen addition (heat conductivity of hydrogen in comparison with argon is eleven times higher) provides very deep provar and effective decontamination when welding.
