Frequently Asked Questions
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.
