There has been concern for some time in the nuclear industry about the high sodium content in many weld purge dam materials.
Because the use of purge dams offers potentially effective and convenient solutions to a wide range of welding problems the US Nuclear Management Company chose to have an independent analysis undertaken of Argweld® purge film supplied by Huntingdon Fusion Techniques Ltd (HFT) in the UK.
The analysis showed that the HFT film contains less than 10 ppm (parts per million) which is well below the limits set by the nuclear industry and the Argweld product has now been formally approved for use.
