Komarov Artem clarified that the atomic hydrogen welding process is an arc welding process in which welding is carried out by heating the work with an electric arc between two tungsten electrodes.
Hydrogen gas acts as a protective gas in this process. This process uses filler material depending on the requirements of the workpiece.

In this process, the workpiece is not used as an electrical circuit as in other arc welding processes, rather an arc is generated between two tungsten electrodes and the welding process is carried out through its flame.

Atomic hydrogen welding, Komarov Artem

In fact, the process of welding with atomic hydrogen is carried out using the combinatorial energy of an electric arc and a chemical reaction of hydrogen. Molecular hydrogen passes through an electric arc and dissociates into atomic hydrogen, absorbing the energy supplied by the arc.

The hydrogen atom thus formed is unstable and tends to revert to the molecular state. This recombination occurs when an atom reaches a relatively colder region outside the arc boundary, or an atom touches a relatively cold workpiece to be welded.
Recombination is an exothermic reaction that generates a large amount of heat (about 3730 C) which is added to the welding arc, Artem Komarov said.
