Welding enclosures designed for additive manufacturing

During welding of titanium and any other reactive metal for additive manufacturing, the welding zone must be purged of oxygen and nitrogen to a level as low as 10 PPM or less of O₂.

Huntingdon Fusion Techniques, HFT® has developed Flexible Welding Enclosures® to encompass volumes of 1,059 cu. ft. and greater. The ultraviolet, stabilized, transparent, low-vapor pressure polymer used for these enclosures is tough and not easily damaged. However, a repair kit is included in case damage occurs.

The purpose-designed enclosures include leaktight zips that can be placed wherever required for access and entry points. Argon entry points are placed at floor level, with matching volume exhaust points at the top. Leaktight glove ports are incorporated at the design stage and can be integrated at any desired positions around the enclosures.
