Product Detailed Introduction
| Welded Materials | Protective Gas | Mixing Ratio | Chemical Properties | Welding Method | Note |
| Aluminum and Aluminum Alloys | Ar+He | MIG: 26%-90% He TIG: Various mixing ratios up to 75% He + 25% Ar | Inert | MIG and TIG | High arc temperature. Suitable for welding aluminum plates, increases penetration depth, reduces porosity, and ensures timely melting. Some spatter occurs as the proportion of He increases. |
| Titanium, Zirconium, and Their Alloys | Ar+He | Ar/He 75/25 | Inert | MIG and TIG | Increases heat input. Suitable for spray arc, pulse arc, and short-circuit arc welding. |
| Copper and Copper Alloys | Ar+He Ar+N2 | Ar/He 50/50 or 70/30 Ar/N2 80/20 | Inert | MIG and TIG MIG | Higher heat input than pure argon, reduces preheating temperature. Lower heat input, but some spatter occurs. |
| Stainless Steel and High-Strength Steel | Ar+O2 Ar+CO2+O2 | Add (1%-2%) O2 Add 2% O2, 5% CO2 | Oxidizing Oxidizing | MIG and TIG | Used for spray arc and pulse arc welding. Used for spray arc, pulse arc, and short-circuit arc welding. |
| Carbon Steel and Low-Carbon Steel | Ar+O2 Ar+CO2 Ar+CO2+O2 CO2+O2 | Add O2 (1%-5%) or 20% Ar/CO2 (70-80)/(30-20) Ar/CO2 95/5 Ar/CO2/O2 80/15/5 Add (20%-25%) O2 | Oxidizing Oxidizing Oxidizing Oxidizing | MIG and TIG MIG and TIG | Used for spray arc welding, suitable for applications requiring high weld seam quality. Good penetration depth, suitable for short-circuit arc, spray arc, and pulse arc welding. Better penetration depth, suitable for spray arc, pulse arc, and short-circuit arc welding. Used for spray arc and short-circuit arc welding. |
| Nickel-Based Alloys | Ar+He Ar+He | Add (15%-20%) He H2<6% | Inert Reducing | MIG and TIG TIG | Increases heat input. Helps suppress CO porosity. |
