Soudage CO2. [Les] lasers CO2 [...] forment une classe de dispositifs très diversifiée. Ce sont des lasers à gaz dits moléculaires, car ils mettent en œuvre les niveaux de vitration-rotation de molécules de CO2 dans un mélange d'azote et d'hélium à basse pression [...] Les molécules d'azote excitées par une décharge électrique et, par collisions inélastiques, transfèrent l'énergie acquise aux molécules de CO2 qui sont l'objet de l'émission stimulée. L'hélium n'a qu'un rôle thermique, mais non moins important. 1, record 1, French, - soudage%20CO2

Dans la méthode de soudage sous protection gazeuse, le gaz neutre utilisé est l'hélium ou l'argon. Les Américains utilisent l'hélium qu'ils trouvent dans certains gisements de gaz naturel. Les européens, quant à eux, utilisent l'argon qu'ils extraient de l'air où il se trouve dans la proportion de 1/100 comparativement à l'hélium qui lui aussi s'y trouve, mais dans la très faible proportion de 1/200 000. 4, record 2, French, - soudage%20par%20le%20proc%C3%A9d%C3%A9%20Heliarc
