From our inception, Stirweld has been at the forefront of FSW innovation. Our path is marked by a steadfast commitment to democratize this advanced technology. With each step, we have turned industry challenges into opportunities, bringing friction stir welding into a new era of accessibility and excellence.
Inception of the project
Laurent Dubourg, our CEO, explored FSW technology since 2005 and faced a primary challenge: the high cost of FSW machines. This led him to ponder, “Why not use a CNC machine for FSW?”
First development
Gilles Sevestre, our CTO, developed the first FSW head for CNC.
Stirweld’s birth
Stirweld was founded as a French start-up with the ambition of democratizing Friction Stir Welding worldwide. We become a Tier 1 supplier for the Ariane 6 program.
International development
Stirweld had already sold six FSW heads internationally and had a team of six members.
Fundraising of 2 millions €
Stirweld accelerated its growth, raising €2 million in funds and expanding its team by 10 people.
1 million € of turnover
Stirweld continued to grow, with a turnover surpassing 1 million euros and a dedicated team of 16 people.
Stirweld lands in USA
