When welding titanium or nickel alloy parts, it is important that the welding zone is purged of oxygen to a level as low as 10 parts per million (ppm).
Flexible Welding Enclosures® are available for a fraction of the cost of a rigid welding chamber, providing a technically viable option to the very expensive rigid metal chambers. Size for size, these Enclosures cost considerably less than a metal glove box or a vacuum system, with a very fast purging time down to a few ppm of oxygen. The Welding Enclosures are ideal for small production quantities of items that need total gas coverage as well as single large items with critical joints.
A combination of translucent material and optically clear sheet is used depending on the viewing requirements of the customer. Large access zips are fitted to each Enclosure and additional entry points can be provided for operators’ gloves. A service panel incorporates access ports for welding torches, electrical leads and water-cooling supplies and a purge gas entry port and exhaust valve are also manufactured as standard to vent displaced gas into the atmosphere.
Flexible Welding Enclosures® are used by companies such as British Airways, Airbus, Pratt and Whitney, Lufthansa, Senior Engineering and Shapes Aerospace International along with many other companies in the Aerospace field and many other Industries such as Titanium Bicycle Manufacturing Companies.
Operator comfort and ease of use versus the disagreeable conditions found with a rigid plastic or metal chamber make the flexible versions a big hit with welding personnel, available in the USA from COB Industries.
Shapes Aerospace have quoted: “We use our Argweld® Flexible Welding Enclosure® along with the PurgEye® Weld Purge Monitor® everyday for our titanium welding. They are built to last!"
COB Industries said: “There are many requirements for welding zones to be purged of oxygen down to as low as 10 ppm, which can be a problem when companies see the high costs of traditional metal chambers. Our Flexible Welding Enclosures® are an ideal solution.”
Special Flexible Welding Enclosures® can be designed and manufactured to suit any purpose with Enclosures recently manufactured for complete robot manufacturing cells and for laser additive manufacturing applications.
