Summary: | The disclosed invention is a composition and process for employing a shielding gas in arc welding. The disclosed composition includes oxygen in an amount between about 0.6% and about 1.9%, helium in an amount between about 10% and about 24%, and the remainder consisting essentially of argon. The invention can be used in high-speed automated welding to result in significantly improved welding speed, joint fit-up tolerance, and burn-through minimization while maintaining excellent mechanical characteristics.
L'invention concerne une composition et un procédé d'utilisation d'un gaz protecteur lors du soudage électrique à l'arc. La composition de cette invention renferme de l'oxygène selon une quantité comprise entre environ 0,6 % et environ 1,9 %, de l'hélium selon une quantité comprise entre environ 10 % et environ 24 % et le reste étant essentiellement constitué d'argon. L'invention peut servir lors du soudage automatisé haute vitesse afin d'améliorer la vitesse de soudage de manière considérable, dans la tolérance à la fixation de joints et dans la minimisation de trous tout en maintenant d'excellentes caractéristiques mécaniques. |
