Modern metallic materials used in high loading structures are increasingly being placedunder stringent standards with regard to the mechanical strength and deformation properties of theirindividual parts as well as with regard to the loading capacity of their junctions. In order todetermine the strain profile of the individual structural components, the mentioned topics will betaken from the SFB 675 “High tensile, locally manipulated structural components and structures”from the subproject C4 “Setting of gradient material properties and qualification of high-tension3D-NVEB weld joints”. To this end, the strengthened individual structural components will beheated with an electron beam at defined locations. This is done in order to observe the load relatedlocal micro-structure changes and consequently the targeted, structured local changes in the strengthand deformation properties of the material. A delay in the crack growth will also be sought after.Additionally, components with specifically designed tensile strength will be welded to high qualitystructures. At this the young but efficient non vacuum electron beam welding method will bepreferably developed, qualified and used because of its good welding properties regarding to animproved beam positioning, process control and weld joint defect detection
