Weld Trailing Shields are an important addition during the welding of stainless steel and titanium tubes, pipes and sheet metalwork, to ensure that the weld environment is totally free from oxygen.
Trailing Shields provide an additional inert gas coverage to that of the welding torch, during and after welding, which forms a protective layer over the weld, preventing it from coming into contact with oxygen and oxidising.
Stainless steels and titanium are reactive metals and therefore hot weld metal will attract any oxygen that is present during welding which will lead to a loss of the metals’ resistance to corrosion.
What is a Weld Trailing Shield?
A Weld Trailing Shield is a small piece of lightweight tooling that attaches to any welding torch including TIG/GTAW, PAW/Plasma and MIG/GMAW.
The Trailing Shield is connected to an argon gas supply, diffusing gas evenly through the stainless steel mesh built into the body of the shield.
At each side, silicone rubber side shields provide a barrier to prevent the gas escaping sideways thus remaining over the weld metal.
As the welding torch is moved forward, the weld remains under an inert gas shield until the welded metal has cooled below its oxidation temperature.
Weld Trailing Shields are manufactured for tubes, pipes and flat sheets of metal.
These shields are in use Worldwide for titanium, zirconium, duplex and stainless steel welding.

Some frequently asked questions:
Do the Trailing Shields fit any welding torch?
Yes, they are designed with a universal worm drive circular clip that will open and close around any shield gas nozzle on any TIG (GTAW), MIG (GMAW) or Plasma (PAW) manual or machine torch.
