Huntingdon Fusion Techniques (HFT®) has developed a low-cost flexible welding chamber to ensure welding zones are sufficiently purged of oxygen (O2) during operation.
The UK-based business claims that the Flexible Welding Enclosures® are a fraction of the cost and provide space-saving solutions, compared to traditional rigid welding chambers.
The enclosures provide fast purging times down to a few parts-per-million (ppm) of O2 and are designed for small production quantities of items needing total gas coverage.
The standard enclosures are manufactured with two sets of glove ports and the upper half of the enclosure is transparent, providing clear welding vision. The addition of a transfer sleeve allows operators to pass small parts in and out of the chamber without affecting purge quality.
Luke Keane, Technical Support at HFT, explained, “For many years, the enormous cost of a metal enclosure prevented all but the major companies taking on work involving the fabrication of these metals. To the rescue came HFT a decade or so ago with the introduction of these flexible welding bubbles.”
The Flexible Welding Enclosures are currently being used in the semiconductor, medical, biochemical and food and beverage industries, amongst others.
