accessories needed to manufacture dams that will not come loose during welding.


Other technical advantages of using water-soluble film instead of other materials include:


• The total transparency of the film dams, allows the welder to see the weld root as it is being laid. • Vapour pressure of the film


is very low and does not outgas harmful elements during welding that can mix with the hot metal and cause metallurgical defects. • The Argweld® products do.


Film does not contain water, like paper and sponge


Low cost weld purging can prove complex, with many welders making savings by constructing their own foam or paper dams in order to reduce the purge volume, making weld purging times shorter.


Such improvised purge dams have severe technical limitations that can lead to loss of welds when they leak or slip from position thus flooding the welding zone with oxygen. To overcome these challenges Huntingdon Fusion Techniques HFT® have designed and developed the Argweld®
