TRA-C industry

What TRA-C industry does

TRA-C industrie is a French industrial group headquartered in the Lyon region (Vindry-sur-Turdine), founded in 2001 and operating 10 production sites in France plus one FSW workshop in Canada. Its core competence is Friction Stir Welding (FSW), a solid-state joining process that uses a rotating shoulder-and-pin tool to plasticize and mix metals without reaching their melting point — enabling welds in aluminum alloys, dissimilar metals (aluminum-copper, aluminum-steel), and thick sections up to 50 mm in a single pass. TRA-C was the first European SME to industrialize FSW for automotive series production and has refined the process since 2009, with proprietary capabilities in 3D robotic FSW cells, hydraulic force control, and HMI-based process monitoring.

The group's offerings span FSW machines (table-top R&D units, gantry production machines, rail-mounted large-panel machines), FSW tooling, robotic welding cells and special-purpose machines, full-lifecycle engineering services (feasibility, prototyping, tooling), medium- and large-series subcontracting, plus operator training and technical assistance delivered through subsidiaries STA and FORM in PROD. Ten subsidiaries — including Serinox (rail, EN 15085 CL1), Jacques Soudure (aerospace precision sheet metal, EN 9100, OASIS-registered), Ets Glaude (aerospace, Dassault Aviation), and others — provide sector-specific certified capacity. The revenue model combines custom-built capital equipment sales, per-project and series subcontracting contracts, recurring tooling and maintenance, and professional services for engineering and training.

Customers are concentrated in highly regulated European industrial primes: Nexter (defense vehicles), Valeo (e-mobility thermal management), Thales Alenia Space, Safran, Thales, Stelia, Dassault Aviation, with aluminum supplied by Constellium and machine tools by Hurco. Distribution is direct, sales-led, with no self-serve or e-commerce channels — quoting is project-specific and delivered through engineering teams. Marketing is content- and event-driven (technical blog, Euronaval, Global Industrie, LinkedIn, YouTube) reinforced by membership in La French Fab, UIMM, and Bpifrance Excellence. The group holds EN 9100, EN 15085 CL1, ISO 3834, EN 1090-1, ISO 9001, ISO 14001, and EcoVadis Silver, and operates across the aerospace, defense, rail, e-mobility, shipbuilding, and energy sectors.

Revenue model

1. FSW Equipment and Machine Sales: Design, manufacture, and sale of FSW machines — including table machines (for R&D and training), gantry/portal machines (for series production), and rail-mounted machines (for large structural panels). Machines are custom-built to client specifications, incorporating force control, HMI, and robotic integration capabilities. Revenue is generated through capital equipment sales, installation, and commissioning.
2. FSW Subcontracting and Production Services: Medium- and large-series subcontracting production of welded components and complex assemblies in company workshops. Services include welding, fine sheet metal work, boiler-making, laser cutting, industrial painting, and machining — all delivered under various industry certifications (EN 9100, EN 15085, EN 3834, EN 1090-1). Revenue is generated through per-project or recurring manufacturing contracts with industrial clients.
3. FSW Tooling Sales and Maintenance: Design and supply of specialized FSW welding tools (shoulders and pins) manufactured from ultra-resistant materials. Also includes FSW machine maintenance services and technical support contracts, providing ongoing revenue from the installed machine base.
4. Engineering, Design, and Prototyping Services: Engineering and design office services covering feasibility studies, product design, tooling design, and prototyping. Bureau d'études composed of PhDs, engineers, and designers supports product development from concept through industrialization.
5. Training and Technical Assistance: Training delivery through dedicated subsidiaries — Soudage Technique d'Auvergne (STA) and FORM in PROD — offering courses at training centers and on client sites, as well as technical assistance and on-site technology transfer.
