A round argon chamber designed for use when welding critical components requiring a fully gas shielded environment.  The Walter Schnorrer® purge chamber is constructed of a heat resistant clear polycarbonate dome to withstand heat or damage from the heat generated in the welding process.  The clear plastic top of the chamber allows the welder to clearly see into the dome for high precision welding applications.

Providing excellent results when welding critical fabrications in Stainless Steel, Titanium or other exotic materials. It has been widely used in aerospace and nuclear industries.


Superior to an inflatable chamber, the Walter Schnorrer Argon chamber is less susceptible to damage and provides a long working life.  A gas diffuser system ensures that a laminar flow of gas enters the chamber to prevent turbulence.

A typical purge time for a 1000mm diameter chamber is 20 minutes at a gas flow rate of 100 litres per minute.


Available in a circular configuration in 1000mm or 1500mm internal diameters.


Why Purge

When welding, a shielding gas is used to protect the molten weld pool from the atmosphere.  If welding a joint though, the shielding gas from the torch is not shielding the back of the weld.  The rear of the weld can then allow entry of the air, creating contamination.  This contamination can then lead to decreased weld strength and decreased anti corrosive properties within the solidified weld.  By creating an oxygen-free environment on the backside of the weld, back purging prevents oxidation, maintains the inherent properties of the parent material, and ensures the longevity and reliability of welded components. Furthermore, effective back purging ensures that the welded joint retains its corrosion-resistant properties, making it suitable for applications where maintaining hygiene and preventing contamination is critical.  A purge chamber ensures that the entirety of the part within is shielded by Argon.


Please note that the Walter Schnorrer product line, including the purge chambers may take 2 weeks to arrive.  Feel free to call or email to check before ordering.
