The latest advancements in the development of linear friction welding (LFW) will be the focus of an international two-day seminar taking place at TWI’s Cambridge UK headquarters in March.
Companies and organisations interested in exploiting or discovering the potential of LFW are invited to attend the 4th International Linear Friction Welding Seminar, which will take place on 16 and 17 March.
Since its inception in 2011 the seminar has grown into a significant industry event attracting delegates from world-leading industrial companies, universities, and research and technology organisations to share LFW developments.
With sessions on equipment development, industrial development and R&D work, the previous seminar, which was held in 2015, attracted 65 attendees and saw almost 30 companies and organisations represented from across eight countries.
This year’s seminar, which will be held at TWI’s on-site conference facility, the Granta Centre, includes sessions on equipment development, industrial applications, R&D, academic simulations and academic practical, as well as a tour of TWI’s friction laboratories and technical demonstrations. Speakers include representatives from industry and academia.
Linear friction welding has established itself as the primary method of fabrication of bladed disk (Blisk) assemblies for aircraft turbine engines. It has great potential for other aerospace applications too, including the manufacture of aircraft structural components. Other sectors that linear friction welding has the potential to benefit include automotive, shipbuilding, rail, oil and gas, energy and construction.

Linear friction welding
Linear friction welding is a solid-state joining process pioneered by TWI that has become an established technology for several niche aerospace applications.
The method involves two parts being pushed together, one oscillating at a high frequency. This creates friction that heats the metals to a temperature at which they are able to join together. When the oscillation stops, the parts cool to form a forged-quality weld.
Linear friction welding materials has a number of advantages. It is a very consistent and fast process, taking as little as a single second to create a weld. Very little preparation of the surfaces to be joined is required: any imperfections and impurities are removed along with a layer of surface metal as flash. It requires no consumables, produces no harmful fumes that require exhausting, and due to it being a solid-state process, bypasses any of the potential issues associated with solidification, such as segregation or porosity.
TWI has been refining LFW for more than 30 years and continues to pursue opportunities for the technology. Our services in this area extend to the following:
- Three LFW machines with an axial force capability of 250kN (25 tonnes)
- Equipment and tooling design guidance
- Development of production applications
- Batch production runs
- Weld quality assessment.
