Vacuum Vessel Sector Fabrication - PossibilitiesVacuum Vessel Sector Fabrication Based on FH Blocks
Manufacturing of the ITER vacuum vessel double wall structure isextremely demanding
Quality-, shape- and dimensional requirements are set to the highest level to meet the specified functional requirements
Welding distortionsResidual stresses
Advanced fabrication methods are needed to ensure the overall quality during the manufacturing process
Reducing weldingIncreasing weld efficiency
