Abstract
During the regeneration of damaged components such as compressor blades, the weld repair is followed by machining processes. Excess weld material is removed in a cutting process in order to reproduce the final contour. Therefore, both processe have to be considered regarding the resulting surface and functional properties of the repaired component. In this study, bead on plate welds are produced on 10 mm Ti-6Al-4 V sheets using micro-plasma welding with different levels of welding current. They are subsequently re-contoured via ball end milling using tools of different cutting edge radii. The residual stress depth profile is measured using X-ray diffractometry. It is shown that the final residual stress depth profile is mainly influenced by the milling process when machining with rounded cutting edges.
