Flexible Welding Enclosures

Argweld flexible welding enclosures provide an enclosed inert-gas environment for welding components that need shielding beyond the immediate torch area. Applications include titanium, nickel alloys, stainless steel and other reactive metals, particularly when a flexible chamber suits the workspace or production volume better than a rigid enclosure.

Standard circular sizes and loading access

The following are the established nominal size references and zip lengths in Justram’s listing. Nominal inch and metric labels are not exact conversions. Confirm the current enclosure drawing, working space and usable loading opening before selecting a size.

Zip length is not the same as a clear opening diameter. Check that the component, fixture and loading path fit through the entry and leave room for the welding operation.

Enclosure features

• Argon entry and exhaust for displacement of the chamber atmosphere.
• Translucent sides and an optically clear top for visibility.
• Standard circular configuration with two pairs of sleeves and gloves, with drawstrings at the glove ports.
• Service feed-throughs for torch, return cable, electrical services and cooling lines as required.
• Additional torch access to accommodate operator position.
• Repair kit for appropriate repairs following the supplied instructions.
• Standard posting sleeve listed as 600 mm long and 230 mm wide when flat, with purge entry and vent; confirm the usable transfer opening.

Rectangular and custom configurations

Rectangular enclosure references include lengths of 900, 1200, 1500 and 1800 mm, larger posting ports and three sets of glove ports. Additional glove ports, posting-port arrangements, other shapes and special sizes can be reviewed for the application. Confirm dimensions and included features on the quoted configuration.

Purge control and installation

Use a suitable weld purge monitor to verify the oxygen level required by the welding procedure. Purge time and achievable oxygen concentration depend on the setup, sealing, gas supply and loading procedure. Follow the enclosure instructions for gas flow, exhaust, ventilation and protection from heat or mechanical damage.

Not supplied: Justram’s listed package excludes the internal metal base plate, internal purge line and external support stand.

Request an enclosure

Provide component and fixture dimensions, loading requirements, operator access, welding process, material, oxygen target and required service connections. Justram can confirm the current drawing, package contents and availability before ordering.
