Most weld purging is carried out on joints made by the TIG or GTAW arc welding process. [6] When the laser welding process is chosen, joints or welds being made on reactive materials will need to be carried out and in the case of electron beam welding, this is carried out in a vacuum, in which case purging takes place by complete evacuation of all gas.
The term inert gas is context-dependent because several of the inert gases, including nitrogen and carbon dioxide, can be made to react under certain conditions. [ 1 ] [ 2 ] Purified argon gas is the most commonly used inert gas due to its high natural abundance (78.3% N 2 , 1% Ar in air) [ 3 ] and low relative cost.
A-25 (25% argon/75% helium) is used for nonferrous base when higher heat input and good weld appearance are needed. A-50 (50% argon/50% helium) is used for nonferrous metals thinner than 0.75 inch for high-speed mechanized welding. A-75 (75% argon/25% helium) is used for mechanized welding of thick aluminium. Reduces weld porosity in copper. [14]
The term “industrial gases” [32] is sometimes narrowly defined as just the major gases sold, which are: nitrogen, oxygen, carbon dioxide, argon, hydrogen, acetylene and helium. [33] Many names are given to gases outside of this main list by the different industrial gas companies, but generally the gases fall into the categories "specialty ...
Nitrogen lasers can operate superradiantly (without a resonator cavity). Amateur laser construction. See TEA laser. Carbon dioxide laser: 10.6 μm, (9.4 μm) Transverse (high-power) or longitudinal (low-power) electrical discharge Material processing (laser cutting, laser beam welding, etc.), surgery, dental laser, military lasers. Carbon ...
