Precision Ar Shield Gas Blend — analytically controlled argon-based shielding mixtures
A Precision Ar Shield Gas Blend from REAL GAZ is prepared to narrow composition limits for welders who need the same arc behaviour on every job.
Argon is the carrier, with oxygen, carbon dioxide or helium added in exact proportions and verified by analysis before release.
Argon is the carrier, with oxygen, carbon dioxide or helium added in exact proportions and verified by analysis before release.
Where welding procedures are qualified to EN ISO 15614, a shielding gas that changes composition can invalidate the qualification record. Precision blending removes that variable. Typical offers include argon with 2% oxygen for stainless steel, argon with 8% CO₂ for mild steel, and argon-helium mixtures for aluminium and copper where extra heat input is needed.
Practical points: composition is only as good as the delivery system, so use clean hoses and fittings and purge the line before the first weld of the day. Do not top up part-used cylinders with another gas, and record the lot number on the weld log when procedures require traceability. For minor additions such as 1 to 3% oxygen, it is helpful to keep cylinders at a steady temperature, and to avoid using the last few bar of pressure on critical welds.
REAL GAZ supplies this product according to ISO 6142-1, ISO 6143 and EN ISO 14175, with analysis carried out under ISO 17025 principles.
🏭 Where Precision Shield Blends Are Used
- 🔧 Qualified weld procedures — fixed composition supports repeatable results when procedures follow EN ISO 15614 and ISO 3834;
- 🍽️ Stainless steel equipment — low-oxygen argon mixtures keep the weld surface bright on food and dairy plant;
- 🔬 Process development — engineering labs compare arc stability and bead geometry using controlled gas compositions;
- ✈️ Aluminium and light alloys — argon-helium variants improve fusion on thicker sections of non-ferrous metal.
💡 Why Choose REAL GAZ
