Accessories for Oxygen free Welding
Purge baffles for cylinders - developed by Walter Schnorrer
These baffles are designed for use in large cylinders and pipes starting at 145 mm (5.7") ID up to 1 meter (39 inches) ID. For smaller tubes click here 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.

Purge baffle for cylinders

Features of cylindrical purge baffles

  • Use for all purge gases in MIG/MAG, TIG and plasma welding processes
  • Reduces purging time saves gas
  • Ensures uniform distribution of the purge gas.
  • Deep seals make baffle easy to move round bends
  • Heat resistant seals to 340 degs C (Plus type)
  • Laminar gas flow from built in diffuser.
  • Always stay in line - works for bends.
  • Units for tube sizes from 145 mm to 1000 mm

Principle of Operation
The baffles comprise a pair of flexible seals on the rim of wheel like structure fabricated of corrugated CrNi steel. A special gas diffuser produces a uniform laminar flow of the purge gas into the space between the seals. There are two different types of baffles depending on the seals used. The plus type has deeper lips giving the baffle a wider range of us usable diameters to which it can be applied. Also the deeper lips are better for dragging the baffles round bends in the pipe.
