ARGWELD®Water Soluble Weld Purge Film 2 Disadvantages of usingprovisional dam systems ■ Time consuming to fabricate ■Made with high vapour pressure materials ■ Full of voids, gas and water vapour May leak and allow harmful gases back into the welding environment & Leave residue
ARGWELD®Water Soluble Weld Purge Film 3 Provisional Dam Systems
ARGWELD®Water Soluble Weld Purge Film 4 Argweld® Water Soluble Weld Purge Film Easy to apply Quick and easy to install, sticks very well insides pipes because of special adhesive No residue Dissolves completely down to molecular level, unlike paper dams which leaves wood fibre residue High melting point Higher temperature resistance than other water soluble products The film and adhesive are completely biodegradable and all packaging materials are recyclable Highest standards Low Halide levels Halide level in film well below international nuclear standards

ARGWELD®Water Soluble Weld Purge Film 7 Specially developed for: ■ Argweld® Purge Film is cost effective and ideally suited to small jobs with variable pipe welding diameters ■ In addition to closing welds, Argweld® Water Soluble Weld Purge Film is used by welding training courses and the vessel fabrication industries for short stubs and trial weld pieces ■ Closing welds in particular, where it is not possible to retrieve a rigid Weld Purge System after the final weld
ARGWELD®Water Soluble Weld Purge Film 8 Purge Film Kit British manufactured product. Comes in a kit consisting: ■ A 20 metre length of 1 metre wide film folded in half and wound on a spool ■ A comprehensive manual with instructions for use with hints and tips for weld purging ■ A slitting knife to quickly cut the dams ■ Two bottles of the adhesive
ARGWELD®Water Soluble Weld Purge Film 9 How it works 1 1-Make a template out of cardboard, that is just slightly smaller than the inside diameter of the pipe to be welded. 2-Make a small holding device and attach it to the template (the picture Purge-film-Template 3.jpg shows an HFT 1/2” pipe plug that has been dismantled and used as a holding device) 3-Check that the template fits inside the pipe OK.
ARGWELD®Water Soluble Weld Purge Film 10 How it works 2 4-Then place the template on the film once it has been rolled out. Cut the Film about 1” (25 mm) larger in diameter than the template” 5-Separate the two layers to make two dams from one cut. (The Film is 39”/1 mtr wide folded in half. So making dams for pipes under 18”/450 mm diameter, will provide two dams in one cut) 6-Place the template on the cut dam, fold the overlapping edges over the back of the template and stick in place. A moist finger print will provide sufficient adhesion
ARGWELD®Water Soluble Weld Purge Film 11 How it works 3 7-Clean the inside of the pipe to be welded, smear the surface with adhesive, where the dam is to be placed. 8-Insert the template with the first Water soluble film dam attached and peel the overlap off the template and push it onto the inside of the pipe where the adhesive has been smeared. 9-Film dam in place
ARGWELD®Water Soluble Weld Purge Film 12 Impenetrable Purge Barrier The weld purge material makes dams that not only produce impenetrable purge barriers but that can easily be washed away. It dissolves completely without leaving any fibres to clog up filters or leaving sensitive materials in the system
ARGWELD®Water Soluble Weld Purge Film 13 Trace Certification Trace element certification can be provided to show that Argweld® water soluble weld purge film does not contain any harmful elements and that the quantity of halides is well below the permissible levels. The film and adhesive are completely biodegradable and all packaging materials are recyclable.
