Huntingdon Fusion Techniques (HFT), specialist in gas weld purging techniques, has written a new White Paper – Welding of Zirconium and its Alloys.
The exclusive paper discusses the physical properties of Zirconium and its principal alloy zircaloy, deeming it to be unmatched by most other metallic materials due to the combination of mechanical strength, corrosion resistance and their high temperature stability. These qualities make them attractive for use in sectors as diverse as biochemical, nuclear, aerospace and petrochemicals. More specifically, zircalloy, is used in the manufacture of pressure vessels, heat exchangers and nuclear power plants.
The White Paper goes on to consider the welding preparations involved with Zirconium to avoid contamination and the two welding processes – Electron Beam (EBW) and Gas Tungsten Arc (GTAW).
Controlling purge gas coverage is another subject covered which explicates the wide range of ancillary equipment available to ensure optimised coverage of the weld zone with inert purge gas. For example; expandable plugs, inflatable weld purging systems, inflatable dams, welding enclosures, inflatable tubes, pipes and pipeline systems.
The full paper can be accessed from the HFT website.
Zirconium alloy welded with effective inert gas protection showing no discolouration.
Huntingdon Fusion Techniques has introduced PurgElite®, a range of low cost tube and pipe purging systems to achieve a clean, oxide free, zero colour weld in just minutes.
From buildings and bridges, to planes, trains and automobiles, much of what holds our world together requires a weld. According to to Zion Market Research, the global market for welding products continues to expand, fueled by growth in end-use industries like infrastructure development and manufacturing.
