Atomic Hydrogen Welding 9 ❑ Atomic hydrogen welding (AHW) is an process that makes 9/30/201 use of an arc between two metal within an atmosphere composed of hydrogen. Shielding is obtained from the hydrogen.

❑ The electric arc produced in the process efficiently breaks up the molecules of hydrogen that later recombine through an extreme release of

heat. Welding Technology/4.2 Atomic Hydrogen Welding Welding Hydrogen Atomic Technology/4.2 Welding

limitations 9 ❑ Cost of welding by this process is slightly higher than with the other 9/30/201 process.

❑ Welding is limited to flat positions only.

❑ Because of the high levels of heat produced in this welding process, need to be even more aware of the dangers they are exposed to.

❑ Skilled is required.

❑ Due to advances in inert gases AHW may be limited. Welding Technology/4.2 Atomic Hydrogen Welding Welding Hydrogen Atomic Technology/4.2 Welding ❑ Hydrogen is highly inflammable gas so it should be taken care.

Applications 9 ❑ Atomic hydrogen welding is used in those applications where rapid 9/30/201 welding is necessary, as for stainless steels and other special alloys.

❑ For most of the ferrous and non ferrous metals.

❑ For thick as well as thin sheets or small diameter wires (2-10mm).

❑ Can be applied almost to any metal, specially in light gauge metal,

special ferrous alloys, and most non ferrous metals and alloys. Welding Technology/4.2 Atomic Hydrogen Welding Welding Hydrogen Atomic Technology/4.2 Welding
