Argon TIG (Tungsten Inert Gas) Glove Box

“Titanium welding” Project

Jacomex has always been a major player in the sector of welding enclosures and glove boxes for TIG (Tungsten Inert Gas) welding under argon. Jacomex has supplied international aeronautical industrialist with a series of glove boxes intended for welding or repairing large titanium parts for many years. The company is a renowned supplier for the largest contractors and subcontractors in the aeronautical and space industry such as:  Airbus, EADS, Airbus, Airbus Helicopters, Dassault Aviation, Sabca, Safran, Zodiac Aerospace, Thales Alenia Space, Stelia, Daher, Tecalemit, Airgrup, Fokker, Air France …

Based on high-end modular GP(Concept) glove boxes, customers benefit from the flexibility that Jacomex can offer in terms of technical solutions when any issues arise.

The glove boxes are equipped with two vacuum transfer locks enabling a continuous flow of the parts to be welded. The two airlocks have been oversized compared to the current vacuum airlocks in order to allow the transfer of large parts: a technical achievement because they work on the same principle as the smaller cylindrical airlocks, namely by creating a vacuum then filling with pure argon. Powerful pumping groups minimize the transfer time, which is essential in production, while preserving the purity of the welding enclosure. A large capacity argon purification unit maintains stable oxygen and moisture purity at very low ppm levels.

In addition to the traditional oxygen and humidity sensors, the installation is equipped with a nitrogen analyzer (to avoid the risks of nitriding) and also a hydrogen analyzer. In this way, the glove box allows you to securely make titanium parts that meet the constraints of the aeronautical industry.

Finally, general ergonomics were optimized to facilitate the movement and handling of heavy parts. Traditionally, acceptance tests are offered in real conditions with coloring tests on samples.

Thanks to feedback from long-standing customers, Jacomex designs and produces argon welding chambers cost-efficiently offering numerous technical advantages in the face of the problems usually encountered in welding titanium parts, noble alloys, and super-alloys.

  • Jacomex glove boxes are equipped with closed loop argon purifiers ensuring better gas quality than other enclosure methods. They allow significant savings in Argon and better availability of welding stations.
  • The stability of gas purity and the quality of the atmosphere itself (in excess of aeronautical industry specifications) that can be achieved in Jacomex glove boxes allow better reproducibility of welds and real control over the methods and means of production.
  • Completed automated, with tracking for the previous 2 months of the main parameters, which allows traceability of welding operations.
  • Additional options available to handle for all situations… trapping of smoke and particles, air conditioning, pneumatic protection screens.

Jacomex designs glove boxes for welding titanium parts, noble alloys and superalloys for aeronautics, and for other sectors such as: additive manufacturing, automotive industry, medical applications, advanced materials research, nuclear industry, etc.
