Shieldpro 23
Shieldpro 23 (formerly Supagas Supashield 2/98) is a high performance gas used for the welding of stainless steel
Ar / N2
Shieldpro 23 mixture has the addition of nitrogen, which improves their performance in the areas of welding speed, penetration, profile, surface appearance, metallurgical benefits etc. This in turn improves the two major areas of concern in a welding process - quality and economics.
Uses
- Ideal for TIG welding stainless steel of all thicknesses
- The addition of nitrogen reduces nitrogen loss from the weld metal, resulting in better corrosion properties compared to welding with pure argon
- Mainly for orbital TIG welding
- Increased pitting corrosion resistance
FAQ
-
Best gases to use for TIG welding stainless steel?
The best gases for TIG welding stainless steel include argon, helium, or a mix of both for optimal weld quality.
-
What grade of stainless steel 316 for TIG welding?
Grade 316 stainless steel is ideal for TIG welding due to its excellent corrosion resistance and weldability.
-
Is TIG welding better for stainless exhaust working?
TIG welding is preferred for stainless steel exhaust systems due to its precise control and clean welds, ensuring durability and performance.
-
Why not use argon shield on stainless TIG welding?
Using an argon shield is not recommended for stainless TIG welding because it may not provide adequate protection against oxidation, leading to poor weld quality and corrosion susceptibility.
