43 also suited to the mig soldering of coated
steels
when material thick- ness is over 1.5 mm.
reduces
the amount of harmful ozone generated during
welding
. classification: iso 14175-z mison ® n2 (ar + 1.8% n 2 + 30% he + 0.03% no) mison ® n2 is suited to the tig
welding
of stainless duplex
steels
and nitrogen-alloyed austenitic
steels
. the nitrogen in the gas
reduces
the nitrogen loss in the weld, providing better corrosion resistance and good mechanical characteristics. can also be used in the mig
welding
of high-alloy austenitic and super- duplex
steels
.
reduces
the amount of harmful ozone generated during
welding
. classification: iso 14175-z mison ® h2 (ar + 2% h 2 + 0.03% no) mison ® h2 is suited to the tig
welding
of austenitic stainless
steels
and nickel-based alloys. the hydrogen enables a hotter and more focused arc, a deeper
welding
speed, better penetration and a smooth fusion between the weld and the base material. the hydrogen also prevents weld oxidation.
reduces
the amount of harmful ozone generated during
welding
. classification: iso 14174-z cronigon ® he (ar + 1% o 2 + 30% he) cronigon ® he is a multi-purpose gas for the mag
welding
of stainless
steels
. low spatter and surface slag. helium addition provides better fluidity of the molten pool and deeper penetration. especially for situations where you wish to ensure that the weld has a very low carbon content (<0.030%) in spray arc
welding
. no ozone-reducing effect. classification: iso 17175-m13 mison ® he30 (ar + 30% he + 0.03% no) mison ® he30 is suited to tig
welding
and the mig
welding
of certain high-alloy stainless
steels
, nickel-based alloys, aluminium and copper and their alloys. mison ® he30 provides a very fluid molten pool, better side penetration, higher
welding
speed and it also
reduces
the need for preheating.
reduces
the amount of harmful ozone generated during
welding
. classification: iso 14175-z varigon ® he50 - varigon ® he70 (ar + 50% he ) - (ar + 70% he ) varigon ® shielding gases are suited to tig
welding
and the mig wel- ding of certain high-alloy stainless
steels
, nickel-based alloys, alumini- um and copper and their alloys. by varying the helium content of the shielding gas, you can achieve the desired properties for the optimisation of heat transfer, molten pool management, penetration and
welding
speed. especially suited to the
welding
of thick aluminium and copper. classification: iso 14175-i3 varigon ® h5 (ar + 5% h 2 ) varigon ® h5 is especially suited to the mechanised tig
welding
of austenitic materials. provides a high
welding
speed and oxidation-free weld. can also be used as the root shielding gas for austenitic stainless
steels
. classification: iso 14175-r1 formier ® 10 (n 2 + 10% h 2 ) formier ® 10 is suitable for use as the root shielding gas primarily of austenitic materials. also used for the root protection of unalloyed and low-alloy
steels
. formier ® 10 is a reducing root shielding gas which provides a well- formed, oxide-free root surface. the gas is flammable, so it should not be used for root protection in tank
welding
. classification: iso 14175-n5 shielding gas applications.
