ELKHART, Ind., February 16, 2023 (Newswire.com) - Bond Technologies, a global leader in friction stir welding (FSW) systems, has officially transferred and installed the world's first welding machine for final disposal canisters to Posiva's ONKALO worksite in Olkiluoto, Eurajoki. Based on the world-class friction stir welding method that Bond Technologies is known for, the new machine will support ongoing final disposal efforts at ONKALO, ensuring tight joining of the cover of each copper canister with the canister body it adheres to.
Delivered from the United States to ONKALO, Bond Technologies' welding machine is based on the company's leading technical position in the industry and its engineering team's experience in the design and construction of FSW systems. Upon installation in Posiva's encapsulation plant, the machine will be put to work securing copper canisters for the final disposal of nuclear materials with reliable and effective results.
The machine, which weighs 25,000 kilograms and measures 3.0 m x 5.2 m x 3.8 m, works by gripping the canister body with a force of 4,000 kN, which helps guarantee that the canister stays in place during the welding process. Once in place, friction stir welding is used to properly weld the top of the canister to its body.
Friction stir welding is a process that uses friction-generated high heat to reach the desired temperature and securely weld two or more workpiece materials together. This results in several key benefits relating to weld quality, including the small grain size of the weld metal, equiaxed grains and random texture, and superior mechanical properties of the finished product. These and other benefits of FSW are essential in nuclear fuel final disposal and will support Posiva's ongoing work at the ONKALO repository.
