Atomic Hydrogen Welding

Welding methods have been developed over several decades. These techniques focused on efficiency, energy yield, economic and social considerations with regard to the protection of people and property, as well as consideration of the environmental impact of the technique used. One of the techniques was atomic hydrogen welding. This was one of the most promising technologies, thanks to the use of hydrogen, which is a clean source of energy, and its ability to reach very high temperatures during welding. This ability made it well suited to some types of welding and very thin materials. However, the high cost of installation and certain risks associated with its application have limited its use for many people. The use of specific equipment, the constant checking of electrical equipment before use, and the fact that the technique is only suitable for particular uses, have not really helped its commercial utilization, as was intended when Langmuir introduced it in 1926. Even in 2020, this technology was considered obsolete by the standardization body, which withdrew its ISO 4063 registration granted in 1990 in 1998. Knowing that this method has undeniable advantages for the environment and in terms of efficiency thanks to the use of hydrogen and the possibility of reaching high temperatures, it is imperative to find ways of improving on the technique. The search for clean biomass solutions to produce hydrogen is one of the most reliable solutions for reducing the cost of hydrogen production and reducing the environmental impact. In addition, reliable hydrogen storage solutions need to be developed to reduce the risk of explosion. Finally, research needs to be carried out into making the operating temperature variable, so that the technique can be used in a wide range of applications.
