Achieve better coverage of the heat affected zone (HAZ) when welding pipe with the Walter Schnorrer range of drag shields.  These clever drag shields attach to the TIG welding torch and disperse shielding gas to the recently welded area.  In doing so, the shielding gas continues to cover the weld whilst it is cooling to prevent oxidisation.  This is particularly desirable when welding stainless and titanium pipe, to achieve optimal results.


Fitted with a gas diffuser, the trailing shield provides a laminar flow of argon to prevent turbulence and enhance the shielding effect on the HAZ.


To use, simply connect the quick release hose to the purge gas supply and fix the weld head to the Drag Shield. Welding can then commence while providing a shielded area on the surface of the pipe.


Available in a variety of sizes to suit different pipe diameters.  Choose from Aluminium or Stainless Steel


Key Features

  • Drag Shield for TIG welding of pipe work
  • Available in Stainless Steel or Aluminium
  • Covers pipe sizes 9.5mm – 407 mm outside diameters with Sintered metal diffuser
  • Covers pipe sizes 25mm – 660mm outside diameters with Aluminium diffuser
  • Temperature resistant to 280˚C for up to 1 hour
  • UV resistant
  • Substantial cost savings in gas and time
  • Laminar flow of purge gas means zero turbulence in the weld area during purging
  • Quick release hose fitting


Why Purge

When welding, a shielding gas is used to protect the molten weld pool from the atmosphere.  Contamination from atmospherics can lead to decreased weld strength and decreased anti corrosive properties within the solidified weld.  By creating an oxygen-free environment on the heat affected zone, whilst cooling it prevents oxidation, maintains the inherent properties of the parent material, and ensures the longevity and reliability of welded components. Furthermore, effective shielding ensures that the welded joint retains its corrosion-resistant properties, making it suitable for applications where maintaining hygiene and preventing contamination is critical.


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.
