Accessories for Oxygen Free Welding
Flexible Purge baffles for curved surfaces - developed by Walter Schnorrer
These baffles are designed for use on flat plates and sheets and inner and outer curved seams The baffle attaches to the sheet with vacuum suction chambers on either side of the purge channel. They can be mounted in any orientation. The baffles are used to contain and distribute the purge gas in the region of the weld root. The environment in the root of the weld typically needs to contain less than 50 ppm of oxygen in order to prevent oxidation. The purge baffles can be used alone or in conjunction with an oxygen analyzer to ensure a good welding environment on the back side of the weld.
