DanStir is dedicated to offering a range of services from R&D on tool and process technology, to pre-production trials and full-scale series production as a sub-contractor. Their installation is similar to the newly commissionedfriction stir welding machine at TWI, which is being used in the EuroStir® project. The similarity of the two machines facilitates fully transparent operation between TWI and DanStir. Tools and welding programs are easilytransferred between the two companies, which facilitates easy and simple transition from process development at TWI to full-scale series production at the company in Denmark.
The welding installation has a welding envelope of 3.4 x 15m making it one of the largest installations available worldwide for friction stir welding sub-contract work. With its 15m effective welding length, DanStir offers theopportunity for fabrication of large-scale components. Alternatively, the long envelope can be divided into dedicated welding stations, holding essentially permanent fixture configurations for key customers requiring friction stirwelding services over extended periods of time. With a down force capacity of over 100kN (10t), the facility can weld all aluminium alloys in thicknesses up to 25mm in single-pass welds. Double-sided welds are achievable in evengreater thicknesses, and other materials may also be welded, with maximum thickness capability depending on alloy and temper.
DanStir's machine envelope is 15m long, 3.4m wide and up to 1.6m high to allow welding of a wide variety of up to 25mm thick workpieces in a single pass
DanStir is an Industrial Member of TWI and works under license to use the friction stir welding technology. With TWI as its primary source of process technology know-how, DanStir co-sponsors the Group Sponsored Project on TransportStructures and is a main collaborator in the EUREKA EuroStir® project on 'European Industrialisation of Friction Stir Welding', in which the company collaborates with TWI on welding of duplex stainless steel.
