12.0 The use of shielding gas Welding handbook

Note that shielding gases other than the ones
mentioned in the table above can also be used. The
consumable manufacturer can also specify a certain
shielding gas composition for a specific consumable.
In such a case, the recommendations for the
consumable should be applied.

12.4 Gas flow during MAG and TIG
welding of Hardox and Strenx

Gas flow can be optimized in order to get a well-
balanced welding performance. Too little gas flow
results in inadequate protection of the melt. Excessive
gas flow can become turbulent thus deteriorating the
gas protection. The gas flow for all welding methods
based on shielding gases, as a rule of thumb, can be
set by using the same number of the gas flow measured
in l/min as the inner diameter of the nozzle measured
in mm. ©SSAB
