WebHydrogen In Welding Atomic hydrogen welding is used for welding stainless steel and some special alloys. It produces the third hottest flame, after dicyanoacetylene and cyanogen. It can also be used for almost all the ferrous as well as non-ferrous metals. The presence of hydrogen also acts as a shielding gas, preventing oxidation and contamination by carbon, nitrogen or oxygen, which can severely damage the properties of many metals. It eliminates the need of flux for this purpose.
