atomic hydrogen welding
1Atomic hydrogen welding — (AHW) is an arc welding process that uses an arc between two metal tungsten electrodes in a shielding atmosphere of hydrogen. The process was invented by Irving Langmuir in the course of his studies of atomic hydrogen. The electric arc… …
2Atomic hydrogen welding — Atomic hydrogen welding. См. Атомно водородная сварка. (Источник: «Металлы и сплавы. Справочник.» Под редакцией Ю.П. Солнцева; НПО Профессионал , НПО Мир и семья ; Санкт Петербург, 2003 г.) …
3atomic hydrogen welding — noun : arc welding that utilizes an alternating current arc between two metal electrodes to dissociate hydrogen from a surrounding stream so that when the hydrogen atoms recombine into molecules at the surface of the part being welded they supply …
4atomic arc welding — Welding using heat created by hydrogen atoms, created by an electric arc recombining to form hydrogen molecules. The heat is used to weld delicate joints, and the hydrogen forms a shield over the weld …
5Welding — is a fabrication process that joins materials, usually metals or thermoplastics, by causing coalescence. This is often done by melting the workpieces and adding a filler material to form a pool of molten material (the weld puddle ) that cools to… …
6Hydrogen technologies — are technologies that relate to the production and use of hydrogen. Hydrogen technologies are applicable for many uses.Some hydrogen technologies are carbon neutral and could have a role in preventing climate change and a possible future hydrogen …
7Hydrogen — This article is about the chemistry of hydrogen. For the physics of atomic hydrogen, see Hydrogen atom. For other meanings, see Hydrogen (disambiguation). ← hydrogen → helium …
8Hydrogen damage — is the generic name given to a large number of metal degradation processes due to interaction with hydrogen.Hydrogen is present practically everywhere, in the atmosphere, several kilometres above the earth and inside the earth. Engineering… …
9welding — the process of joining together two pieces of metal so that bonding accompanied by appreciable interatomic penetration takes place at their original boundary surfaces. The boundaries more or less disappear at the weld, and integrating crystals… …
10Hydrogen embrittlement — (or hydrogen grooving) is the process by which various metals, most importantly high strength steel, become brittle and crack following exposure to hydrogen. Hydrogen cracking can pose an engineering problem especially in the context of a… …
