The green guy is welding behind a black screen, which works as a mirror. The heat of the welding is the reason he is visible at all.
TWI is at the forefront of solid phase friction welding and processing technology. Active and innovative in welding research and development since the 1960s, we are responsive to industry needs and provide consultancy services to all industry sectors.
Support for industry includes: advice on component design, process selection & quality issues, troubleshooting, feasibility & pre-production trials, application & prototype equipment development.
TWI has been responsible for many key innovations and developments in solid phase joining; Friction stir welding was invented at TWI and was rapidly applied by industry; Linear friction welding was developed into a mature joining process for turbine blades.

Since its early beginnings as the British Welding Research Association in 1946, TWI has been at the forefront of arc welding development. For instance, we developed carbon dioxide (CO2) shielding for MIG/MAG welding, making the process viable for welding carbon steel, and built the first solid-state power sources, paving the way for thyristor and inverter technology.
