Shielding gases for stainless steels
Shielding gases for stainless steels
Stainless steel type Process Filler material Shielding gas Properties
Ferritic MIG/MAG Solid wire MISON ® 2 Good short and spray arc properties.
For example Short arc Low spatter and surface slag.
AISI 430 Ti, X 3 CrTi 17 Spray arc Smooth weld with a good fusion.
AISI 409, X 2 CrTi 12 Pulse welding Especially for small sheet thicknesses.
Martensitic MISON ® 2He General gas with a wide operating range.
For example Short arc Low spatter and surface slag.
AISI 410, X 12 Cr 13 Spray arc Better penetration and fluidity of molten pool
AISI 420, X 20 Cr 13 Pulse welding than with shielding gas with no added helium.
AISI 420, X 20 Cr 13
Smooth weld with a good fusion.
Enables a high welding speed.
Especially for larger sheet thicknesses.
CRONIGON ® He General gas with a wide operating range.
Short arc Low spatter and surface slag.
Spray arc Better penetration and fluidity of molten pool
Pulse welding than with shielding gas with no added helium.
Even weld bead with a good fusion.
Enables a high welding speed.
Does not carbonise the molten pool.
No ozone-eliminating properties.
Rutile cored wire MISON ® 18 General gas with a wide operating range.
Adjusting welding parameters is easy and
spatter formation is minor.
MISON ® 25 Recommended alternative in addition to the previous.
Especially for cored wires designed for welding
with a more oxidising gas than the MISON ® 18
shielding gas.
TIG With or without MISON ® Ar Provides a stable arc which is easy to ignite.
filler material.
Root protection Argon Inert shielding gas
All MISON ® shielding gases remove ozone generated during welding and improve the welder’s work environment.
