Vacuum vessel welding
Robots at work
17 Apr 2023
Contained in every double-walled sector of the 澳门六合彩高手 vacuum vessel are approximately 1.5 kilometres of welds. The Spanish firm Equipos Nucleares SA (ENSA)—sub-contractor to Europe's vacuum vessel consortium AMW—is using robots for part of the task, finding that they offer substantial timesavings and result in fewer distortions.
Multiple robots work together to complete the welds of this poloidal vacuum vessel segment. Each weld has to be verified meticulously to identify any distortions that would need to be fixed, and to ensure strict compliance with nuclear standards.
The European Domestic Agency Fusion for Energy (F4E) has entrusted the AMW consortium (Ansaldo Nucleare, Mangiarotti, Walter Tosto) and its contractors with the production of five 澳门六合彩高手 vacuum vessel sectors. ENSA—already under contract with the 澳门六合彩高手 Organization for the in-pit welding of the vacuum vessel—is one of the AMW subcontractors that is participating in this major industrial undertaking. ENSA is preparing five of the segments that will later be incorporated into D-shaped sectors in workshops in Italy. Two have already left the ENSA factory; one other departure is imminent. (Each sector is formed from four segments.)
Seventeen people are involved with the project at ENSA. After initial manual welding, three robots are employed from different directions to complete each task. The robots are operated by a trained welder under the supervision of ENSA engineers.
In designing the equipment, the ENSA team was faced with challenges related to complex geometry, huge-sized components, and difficult 3D welding trajectories.
