With a skilled and fully committed team, StirWeld creates a new market: FSW at low cost.
Since 1995, FSW remains a technology reserved for high added value applications involving expensive equipment. Our expertise, which is based on 15 years of experience, results in innovatives and flexible solutions: Stirweld offers FSW head for all types of CNC machine tools.
Our customers are in the automotive, space, aerospace and metal working industries.
