Argweld® Water Soluble Weld Purge Film®

Easy Impenetrable Weld Purge Barrier!

The Argweld® Weld Purge Film® and Argweld® Super Weld Purge Adhesive® material makes dams which produce an impenetrable purge barrier but which can easily be washed away when hydrostatically testing the pipe or just by normal wash out.

Weld purging paper products and purge paper cones leave behind paper fibres which are not good for clean weld purging.

Use Weld Purge Film® which does not contain water, like paper and sponge products do, ensuring the dissolvable purge dam leaves no fibres to harm the weld.

Water soluble weld purge film® is biodegradable, can be used as a purge gas barrier during TIG welding and is effective when a tandem pipe purging bladder is not practical.

For the manufacture of pipe purging dams, Argweld® Water Soluble Weld Purge Film® and Argweld® Super Weld Purge Adhesive® is an easy and cost effective solution.

Frequently Asked Questions

1.0 I want to see the weld root and how it is forming and progressing. Can I do that with Argweld® Water Soluble Weld Purge Film®?

Yes, the Argweld® Water Soluble Weld Purge Film® is transparent which allows welders or their assistants to see the weld root clearly during welding.

2.0 Why should I use Argweld® Water Soluble Weld Purge Film®, rather than other similar products in the market place?

There are several reasons to use Argweld® Water Soluble Weld Purge Film®, some of which are:

It allows welders to see the weld root as the weld is progressing.

It arrives as a complete kit with Weld Purge Film®, Water Soluble Super Adhesive®, Safety Knife and User Instruction Manual.

The price is significantly lower than other water soluble products.

Huntingdon Fusion Techniques and your nearest Distributor keep large volumes of Argweld Water Soluble Weld Purge Film® in stock at all times, so you will never be left half way through a job without supplies.

Argweld® Water Soluble Weld Purge Film® Kits are purpose developed and manufactured for the Pipe Welding industries.

3.0 Can I use Argweld® Water Soluble Weld Purge Film® in a paper and pulp manufacturing plant?

Yes. There are no harmful ingredients which will affect the paper making process. Our chemical analysis report is available on request.

The film dissolves completely down to molecular level and doesn't form clumps the way that water soluble paper will.
Clumps can be made by forming on weld defects inside the pipe and end up, settling on a sheet and maybe causing the loss of a complete roll of paper.

4.0 Can you tell me about the Halides in the film and their levels?

We can provide a Chemical Analysis document to show that the level of Halides in the Argweld® Water Soluble Weld Purge Film® is lower than the minimum levels which cause concern in the welding of stainless steel in, for example, nuclear facilities.

5.0 How do I fix Argweld® Water Soluble Weld Purge Film® inside pipes?

We supply Argweld® Water Soluble Super Adhesive® and comprehensive instructions explaining how a purge film adhesive dries and fixes the purge film dam much better inside pipes.

We also have a video presentation to show how to prepare and use the film dams.

6.0 Is Argweld® Water Soluble Weld Purge Film® the same material as Dissolvo?

There are two products on the market place under the name Dissolvo. One is a water dispersable paper. The other is a PVOH plastic film.

These products are in no way connected with Huntingdon Fusion Techniques HFT® or in our product range.

7.0 I have tried using paper dams and cones do not stick well inside pipes. Will the film work any better?

Argweld® Water Soluble Super Adhesive® fixes the Argweld® Water Soluble Weld Purge Film® dam very securely to the pipe wall and creates an impenetrable barrier until water arrives to wash it away.

8.0 Will Argweld® Water Soluble Weld Purge Film® burn?

Argweld® Water Soluble Weld Purge Film does not ignite if the temperature becomes too hot.

9.0 Where can I obtain Argweld® Water Soluble Weld Purge Film® Kits?

Argweld® Water Soluble Weld Purge Film® is solely and exclusively manufactured by Huntingdon Fusion Techniques HFT® and can be purchased from our Exclusive Distributors for your area.

10.0 How soluble are these purging materials?

The Argweld® Water Soluble Weld Purge Film® dissolves completely down to the molecular level. Other water soluble products may only be water 'dispersible' as the wood fibers do not dissolve and leave residues which can clog filters.

11. Is it possible to leave the Weld Purge Film in place for a couple of days before welding?

Yes, as long as the film is not in contact with any other substance, it will remain in place until it is washed out.

12. Can the film be glued to itself to make a bigger sheet?

We have had instances where customers have glued the Weld Purge Film® sheets together for purging larger diameter pipelines where film is the only option. As it is applied by hand, the user can ensure there is a good sealing when its placed into the pipeline, similar to the way they would check it is sealed against the pipe wall and therefore should be able to achieve a good air-tight seal.
