Helium grade 6.0

Helium in a compressed state of high purity grade 6.0 is a substance that contains 99.999% of gas (i.e., with an impurity content of no more than 0.00001%). This odorless and colorless substance is effectively used in high-tech processes (laser technology, chromatography, welding, etc.), in which the presence of ordinary air can adversely affect a particular operation.

General characteristics

The property of helium not to form chemical compounds and not to dissolve in the weld pool allows the metal to be melted evenly. In this case, the composition of the metal in the weld changes slightly. Helium mixed with argon provides good metal penetration and weld formation and significantly reduces spatter. To achieve a clean seam, it is necessary to use only high-quality electrode wire and monitor the cleanliness of the surfaces to be welded.
