WELDING GAS COMPOSITIONS AND METHOD FOR USE |
摘要 |
The present invention relates generally to welding gas compositions used as shielding gases in an electric arc welding process. More particularly, the invention is directed a shielding gas compositions used in gas metal or tungsten metal arc welding processes for welding aluminum or aluminum alloy containing work pieces. The compositions comprise from 200 to less than 400 ppm oxygen; from 200 to less than 400 ppm of a second gas selected from nitrous oxide, nitrogen, and combinations thereof; and the remainder being an inert gas preferably selected from argon, helium, and mixtures thereof. |
