METHOD FOR ARC-WELDING ALUMINUM-COATED METAL PARTS USING OXIDIZING GAS |
| 摘要 |
The invention relates to an electric arc welding method for welding at least one metal part including an aluminum based surface coating, using a shielding gas. According to the invention, the metal of the aforementioned metal part is melted by the electric arc alone without the use of any laser beam. The invention is characterized in that the shielding gas comprises a mixture of argon and/or helium, nitrogen, and an oxidizing compound selected from oxygen and carbon dioxide. |
