Liquid helium

Helium is colourless, odourless, non-toxic, non-corrosive and non-combustible. With a value of 4.2 degrees Kelvin or –269 °C, it has the lowest boiling point of any gas and as a result, liquid helium is the coldest matter on Earth. This is what makes it ideally suited to be used as cryogen in a number of cutting edge applications including superconductivity in magnetic resonance imaging (MRI), nuclear magnetic resonance (NMR), particle physics and other cryogenic applications.

The choice of shielding gas is important as well as the choice of adding materials, equipment and high qualification of welder. The right choice of shielding gas determines mechanical properties as well as a form of weld, spatters and slag at welding. We offer you certified shielding welding mixtures CORGON®. It is mixtures on the basis of argon, which are developed for obtaining significantly better results in comparison with welding in pure carbon dioxide. Continue reading


The basic component of this mixture is argon, to which is added required quantity (%) of one or several additives. It is usually hydrogen (additional symbol is H%, helium (He%), oxygen (S%) or carbon dioxide (C%). FORMING GAS (90% of nitrogen + 10% of hydrogen) is also belongs to this group. The choice of mixture type depends on welding task. Generally, VARIGON® mixtures are used in order to improve quality and increase welding speed. Such kind of mixture is usually expensive. The main VARIGON® application is MIG-MAG welding and TIG welding of important constructions made of stainless steel, aluminium alloys, etc. Continue reading


Hydrogen - the basic building blocks of the universe. It is the most abundant element, and all elements are formed from it by fusion and nuclear reactions. Hydrogen is used in the chemical, petrochemical, metallurgical, pharmaceutical, electronics and other industries Continue reading


As a gas the special properties of helium are used in many industries and processes such as diving, lifting, leak testing , automotive industry, semiconductor manufacturing, cutting and welding, nanotechnology and for analytical purposes. Continue reading
