Flexible Welding Enclosure® for Welding Down to 10 ppm

When welding titanium and zirconium joints it is important that the welding zone is purged of oxygen to a level as low as 10 parts per million (ppm). A flexible welding chamber is available from Huntingdon Fusion Techniques HFT® for a fraction of the cost of a rigid welding chamber. Flexible Welding Enclosures® provide a technically viable option to what are very expensive rigid enclosures or...

QuickPurge® Your Pipes for Perfect Welds

Time is money. Welders, supervisors, welding engineers, quality control personnel and others are kept waiting, sometimes for many hours, for stainless steel or titanium pipe joints to be purged of oxygen ready for welding. Weld purging is necessary to reduce the oxygen content below 50 parts per million so that the weld surfaces and the adjacent hot metal doesn’t oxidise and thereby cause loss...

No Lost Purge During Welding

Weld Purging stainless steel and exotic metal pipes before, during and after welding is necessary and welders often construct their own purging device made from wood, foam or paper. These unsuitable dams may leak or slip from position, flooding the welding zone with oxygen and resulting in an unsuccessful weld. The alternative to the homemade devices is to fill the entire pipes with expensive...
