Trailing Shields for additional inert gas coverage during stainless steel welding and titanium welding

Argweld Weld Trailing Shields® allow the user to weld faster, save money and produce bright, shiny welds.

The Argweld Weld Trailing Shield® is connected to the argon gas supply, diffusing gas evenly without turbulence through the multi layers of stainless steel mesh built into the body of the shield. At each side, replaceable silicone rubber side shields provide a barrier to prevent the argon escaping sideways and remaining over the weld metal. As the welding torch is moved forward, the weld remains under an argon gas shield until the welded metal has cooled below its oxidation temperature.

Argweld Weld Trailing Shields® are reusable, with a temperature resistance of up to 230ºC. They prevent re-work, eliminate the need for an expensive purge chamber and allow for faster welding.

Suitable for welding titanium, zirconium, nickel, and cobalt alloys, stainless and duplex steels and other reactive metals.

Argweld Weld Trailing Shields® save re-work, reduce gas usage and save wasted material costs by avoiding rejected welds due to oxidation.

Flat models for sheet or plate work are available as well as profiled models for the welding of both internal and external pipes, vessels and tanks.

By using Argweld Weld Trailing Shields®, welds will be left bright and shiny without discolouration and oxidation even when welding at faster speeds.

Argweld Weld Trailing Shields® are kept in stock for most popular sizes of pipes and vessels.

There are many other brands similar to our Argweld Weld Trailing Shields® on the market today, make sure your Shield is stamped with the HFT® logo.

Technical Data and Specification

trailing shield, back purging, huntingdon fusion, purge and weld

Argweld Weld Trailing Shields® are available in 'flat format' for sheet metal welding or in curved format for welding circular items such as tubes, pipes and vessels.

For manual welding, there is one 'flat format' version.

The 'curved format' versions are for all radii of tubes pipes and vessels up to 2000 mm (80") diameter.

Curved versions are radiussed for welding on the outside of tubes, pipes and vessels and for welding on the inside of large diameter tubes pipes and vessels.

For automatic welding systems, where the welding torch is being carried by a mechanism, the Argweld Weld Trailing Shields® can be longer and wider to cater for the faster welding speeds of an automatic system. These are made to specification (made to order).

Non-stock curved versions are also manufactured to specification (made to order) to suit the appropriate radius and shape for inside welding.

Argweld Weld Trailing Shields® are suitable for use on all brands of TIG/GTAW, MIG/GMAW** and Plasma/PAW manual or automatic welding torches.

For manual welding, the welder finds that with this lightweight and low cost tool, there is no difficulty in dragging it along the surface being welded. One further benefit is that it carries the welding torch at 90º to the weld.

Each Argweld Weld Trailing Shield® now features a new unique clip design, which means welders can choose between right and left hand use and can easily change different shield sizes without having to change the welding torch.

Separate leak tight gas hose connections are provided with the Argweld Weld Trailing Shields®, single ones for smaller sizes and double or triple ones for larger sizes. (See individual size specification)

The insides of the Argweld Weld Trailing Shields® are manufactured with several layers of mesh with different hole sizes so that the welding shield gas is dispersed widely, evenly and slowly over the surface being welded, to avoid turbulence and the creation of low pressure areas that would otherwise allow oxygen to enter from the outside.

Consumable side wall seals manufactured from flexible silicone rubber are fitted to each Argweld Weld Trailing Shield® and can easily be replaced when burnt or damaged.

Silicone rubber is resistant to temperatures up to 200ºC (392ºF). However, it will burn and harden when welding slowly at high currents, so the side wall seals must be regarded as consumable.

The replacement seals can be purchased cut to size for each Argweld Weld Trailing Shields®, or the replacement material can be purchased as continuous strip, at lower cost, for users to cut their own side wall seals to length when required.

** Some high current MIG/GMAW welding applications might be too hot for practical use of the Argweld Weld Trailing Shields®.

Justin King

"I have purchased a HFT Argweld Weld Trailing Shield® to suit Ø2” tube and can confirm the product has worked really well. For this specific application we needed to hand TIG weld a Titanium pipe assembly without the risk of any oxygen ingress. This shield design gives us the perfect form to ensure the weld is produced in full compliance with our customers’ requirements. The quality & build of the shield is also of a high quality."

Frequently Asked Questions

Trailing Shields for additional inert gas coverage during stainless steel welding and titanium welding

1.0 What are the benefits of using an Argweld Weld Trailing Shields®?

There are several reasons, some of which are:

A. The chance of a weld defect is dramatically reduced due to the wide gas coverage held over the weld for a longer period during welding, while the heated metal is cooling below the oxidation temperature.

B. Welds are finished in a bright and shiny condition, minimising or eliminating post weld grinding and cleaning.

C. The heat affected zones of a weld are left clean when using an Argweld® Weld Trailing Shields® because of the extra wide gas coverage.

D. Welders can weld faster because of the extra time that the weld remains covered with inert gas when using an Argweld Weld Trailing Shields®.

E. Significant reduction of manufacturing costs due to the reduction of post weld cleaning and the reduction of defects when using an Argweld Weld Trailing Shields®.

2.0 Can I use Argweld Weld Trailing Shields® for stainless steel as well as titanium and zirconium?

Yes, Argweld Weld Trailing Shields® are extremely valuable for all stainless steel, duplex steel and other alloy steel as well as titanium, zirconium and all of the nickel and cobalt alloys.

3.0 Can I buy an Argweld Weld Trailing Shield® which is longer or wider?

Yes. Argweld Weld Trailing Shields® are designed for two methods of use:

A. For manual welding where they are light in weight and easy to manipulate by the manual welder when he has an Argweld Weld Trailing Shield® attached to his welding torch.

B. For automatic welding machines.

For automatic welding machines, where weight and size is less of a concern, Argweld Weld Trailing Shields® are available in longer and wider dimensions to allow for much faster welding speeds and much hotter welds where greater gas coverage is necessary for obtaining clean defect free welds.

4.0 Can Argweld Weld Trailing Shields® be used on any welding torch?

Argweld Weld Trailing Shields® are designed and delivered 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.

5.0 Can I weld flat sheet and plate with Argweld Weld Trailing Shields®?

Yes, one of the the Argweld® products is a flat Argweld Weld Trailing Shields® which is available as an accessory for manual welding torches and another flat version for machine mounted welding torches.

6.0 Can I weld on the outside of pipes and vessels with Argweld Weld Trailing Shields®?

Yes, Argweld Weld Trailing Shields® are kept in stock for most popular sizes of pipes and vessels. Simply tell us the diameter of your pipe or vessel and we will provide an exact match.

7.0 Can I weld on the inside of pipes and vessels with Argweld Weld Trailing Shields®?

Yes, for those people making welds on the insides of pipes and vessels we manufacture the Argweld®Weld Trailing Shields® with an internal radius to suit the exact diameter of the weld being made.

8.0 What are the side shield gaskets made of and what temperature will they withstand?

The side shield gaskets are made of silicon rubber which is temperature resistant up to 200˚C (392˚F). These are low cost, consumable items and once burnt, can be replaced.

9. Are Argweld Weld Trailing Shields® for right or left hand use?

Each Argweld Weld Trailing Shields® has a new unique torch attachment, which means not only can the welder easily change different shield sizes without having to change the welding torch, the unique clip design means the Shields can allow for both right and lend hand use.
