2 Contents Company information Narrow Gap Welding Technologies 3D Cold Forming , 2

3 Company Information Hollming Works is a contract manufacturer for technology industry specialised in Marine and offshore components Energy and enviromental components Process components Pressure vessels , 3

4 Company Information Workshops at four locations Kankaanpää Parkano Loviisa Pori The networked entity of about 900 employees is able to provide Component-, Project- and System deliveries globally Continuous technological development , 4

5 Company Information Hollming Works is certified according to SFS-EN ISO 9001: 2008 quality system SFS-EN ISO welding system ISO environmental system Pressure vessel licenses: ASME, TÜV, PED, Chinese manufacturing license , 5

6 Vacuum Vessel Sector Fabrication Based on FH Blocks Manufacturing of the ITER vacuum vessel double wall structure is extremely demanding Quality-, shape- and dimensional requirements are set to the highest level to meet the specified functional requirements Welding distortions Residual stresses Advanced fabrication methods are needed to ensure the overall quality during the manufacturing process Reducing welding Increasing weld efficiency , 6

7 Vacuum Vessel Sector Fabrication Based on FH Blocks Flexible Housing Block (by Powder HIP) High repetition, reduced welding, testing and distorsion Assembly of Flexible Housing Blocks (by NG TIG, NG MIG, Hybrid Laser or EB) High repetition Formed shell plate (by 3D Cold Forming) High repetition, reduced welding, testing and distorsion Flexible Housing Blocks joined to formed shell plate (by NG TIG, NG MIG, Hybrid Laser or EBW) High repetition , 7

8 Vacuum Vessel Sector Fabrication Based on FH Blocks Installation of neutron shielding plates (by tool assisted manual procedure) High repetition Installation of stiffening elements and end plates (by NG TIG, NG MIG, Hybrid Laser or EB) High repetition Formed shell plate (by 3D Cold Forming) High repetition, reduced welding, testing and distorsion Installation of outer plates (by NG TIG, NG MIG, Hybrid Laser or EB) High repetition , 8

9 Narrow Gap Welding Technologies Hollming Works has used Narrow Gap welding technologies since 1995 Narrow gap TIG (GTAW) and SAW methods in common production use for wall thickness mm NG MIG/MAG still under development 100 mm , 9

10 Narrow Gap Welding Technologies Continuous co-operation with customers to develop welding methods further Special components for Metso Wall thickness mm Weight tons PM HIPed Stainless steels (eg. Super duplex) Quenched and tempered steels (eg. 42CrMo4) Super alloys (eg. Inconel 625) , 10

11 3D Cold Forming Hollming Works has a 3D Cold forming method in continuous production use 3D Cold forming technology offers possibility to Shape optimization and repeatibility Reduce amount of welding , 11

12 3D Cold Forming Using 3-D cold forming can significantly reduce the amount of welding and related problems during the fabrication of the ITER vacuum vessel sector Possibilities of 3D cold forming technology have been investigated in EFDA Task - Advanced Techniques for Vacuum Vessel Sector Manufacturing, Subtask 2: Assessment of 3D forming of inboard walls , 12

13 Hollming Works areas of interest Manufacturing of different subsections for e.g. PS1, PS2 and PS4 using advanced fabrication methods 3D cold forming Narrow gap welding and PM HIP components and blocks Subsections are to be defined later , 13
