Inert gases are used in welding operations to prevent oxidation, improve weld quality, and ensure a smooth weld surface. PSA Nitrogen Generators supply high-purity nitrogen for welding processes, cutting off oxygen exposure and helping the weld area stay clean, strong, and durable.
Our Oxyvital PSA nitrogen generators prevent oxidation in welding processes, enabling safer, uninterrupted, and higher-quality production. By choosing high-purity nitrogen production, you can improve weld quality and operational efficiency.

Why Should You Use a PSA Nitrogen Generator for Weld Shielding?
Nitrogen produced through PSA technology is generated at high purity and with precise control, making a significant contribution to maintaining quality standards in welding processes, reducing reliance on external suppliers, and making operational costs more predictable.
Creating a Protective Atmosphere in the Weld Zone
Nitrogen's inert nature cuts off the metal surface's exposure to oxygen during welding, forming a protective atmosphere and shielding the weld zone from external factors.
Preventing Oxidation and Porosity
Reduces oxidation that can form on the metal surface when exposed to oxygen at high temperatures, eliminating the risk of weld seam weakening and porosity.
Preserving Weld Quality and Surface Integrity
A controlled inert environment helps produce a more homogeneous, durable weld seam, reducing surface defects and improving weld quality.
Eliminating Dependence on External Supply
PSA nitrogen generators produce the gas continuously on-site, reducing the need for cylinder and liquid nitrogen supply, lowering logistics risks, and improving process continuity.

Frequently Asked Questions
+What does nitrogen do in weld shielding?
It removes oxygen from the weld zone, preventing oxidation, and helps produce a cleaner, more durable, defect-free weld seam.
+Which welding methods use nitrogen?
It's preferred as a shielding gas in precision welding applications such as TIG and MIG/MAG, particularly on stainless steel and alloyed metals. It's also widely used in backing gas (purging) applications.
+What's the difference between a PSA nitrogen generator and using cylinder gas?
PSA systems produce nitrogen on-site, providing uninterrupted use. Cylinder gas requires procurement, transport, and inventory tracking. Using a generator removes these operational burdens, delivering more efficient production.
+How does a nitrogen generator affect weld quality?
Stable-purity, continuous gas flow allows the weld pool to form under more controlled conditions. Oxidation is reduced, surface quality improves, and the need for rework decreases.
