For the welding of titanium as well as other metals like stainless steel, Zirconium and its alloys, Huntingdon Fusion Techniques Ltd has developed a range of welding enclosures, so that welding can take place in an inert argon gas environment to eliminate all oxygen, hydrogen and water vapour. These enclosures are intended for production as well as research and development and they are particularly successful in aerospace, racing car manufacture and nuclear related industries as well as for those manufacturing stainless steel parts where cleanliness of the final weld is important. The enclosures are available in four standard sizes, having diameters of 900, 1200, 1500 and 1800 mm and all come complete with two pairs of arm entries with sleeves and gloves, a zip for entry and exit of the components to be welded, an argon hose connection and a gas release valve at the top of the enclosure. A service panel is included with glands for the welding torches and earthing leads, with spare ports for any other services that may be required inside the enclosure once it is in use.
