Here are some of our Frequently Asked Questions about our Weld Purge Film!

Q. What is the typical application for Argweld® Weld Purge Film?

Weld Purge Film is perfect when mechanical purging devices cannot be retrieved. The Film can be used to create an impermeable barrier, but can be easily washed away after use without leaving any residue.

Q. Why should I use Argweld® Water Soluble Weld Purge Film?

There are many reasons, here are just a few:

• It can be purchased at a low cost.
• It allows welders to see the weld root as the weld is progressing.
• Film does not contain water, like the paper option, so there is no water near the vicinity of the weld that might oxidise the weld or cause porosity.
• It arrives as a complete kit with film, Argweld® Water Soluble Super Adhesive®, Safety Knife and User Instruction Manual.
• Argweld® Water Soluble Weld Purge Film® Kits are purposely developed and manufactured for the Pipe Welding industries.

Q. Will Argweld® Water Soluble Weld Purge Film® burn?

Argweld® Water Soluble Weld Purge Film® will disintegrate but will not ignite if the temperature in the weld zone becomes too high

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

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

Q. Can the Weld Purge Film® be glued to itself to make a bigger sheet?

We have had instances where customers have glued the Weld Purge Film® sheets together using a short overlap 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.

Q. 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.

Q. Where can I obtain Weld Purge Film® Kits?

Argweld® Water Soluble Weld Purge Film® is solely and exclusively manufactured by HFT® and can be purchased from our distributors for your area.
