A group serving the aerospace industry

Production and assembly (OEM)
  • You need to improve the quality of your products, ensure compliance and increase productivity
  • We will assist you in all stages of your production processes : staff training, development and optimisation of your metal alloy and composite assembly
  • We check your production parts at your site or at our workshops, either on a one off basis or as part of a long-term contract.
Aircraft maintenance (MRO)
  • Equipment safety and integrity checks, reduced
    maintenance times
  • We can provide worldwide assistance for all aspects of non-destructive maintenance and control operations: EASA PART 145 approval for composite and metallic aircraft parts.
From metal to composite material

Design, manufacture and in-service monitoring

From metallic to composite, we offer solutions in training, inspection, destructive and non-destructive testing, expertise and research & development.

We help the profession better understand the issues and implications of NF ISO 24394 standard. The aerospace industry must comply with the regulations in force in the field of welding parts, used in aerospace and aeronautics applications.

We will assist you in developing the welding and NDT skills of your personnel. We provide training courses and prepare your staff for the theoretical examination to the standards and personnal certification.

We can also carry out characterization of materials and assemblies:

  • mechanical testing,
  • chemical analyses,
  • metallographic testing.

Institut de Soudure Group provides a complete range of appropriate non-destructive testing services for your parts, in our centres or on your site. We can establish validation of control procedures by our FrANDTB level 3 certified agents.

We have been able to demonstrate our expertise through our accreditations, our approvals and the recognition of our customers, whether for production monitoring (OEM) or maintenance monitoring (MRO).

Indeed, Dassault Aviation, Airbus Hélicopters, Safran and Duqueine have trusted us to support them in the production of their components. And Dassault Falcon Service and Embraer, to carry out maintenance monitoring by our authorised EWIS/CDCCL agents.

Would you like to carry out expertise on high-tech parts for aerospace applications?

Thanks to our laboratories, our experts can accompany you in audit and expertise through:

  • damage and failure analysis,
  • metallographic examinations,
  • defect impact studies, etc.

Our agents provide Nadcap PRI certification support for welding in control and for the process of manufacturing and electronic assembly.

Innovation being a key element for the group, we have a team dedicated to research and development as well as engineering.

We provide you with our laboratory equipment (welding, control) and our skills.And we offer tailor-made solutions for your specific needs.
