However, there are many cases where texture characterization needs to be performed in a non-destructive way, where the measurement can be made without damaging the object. Typical examples are archaeological artefacts or very expensive materials. Here we demonstrate the application of an X-ray diffractometer mounted on a robotic arm designed for residual stress scanning for texture characterization, enabling the determination of the orientation distribution function for different locations on samples with complex geometries. The texture characterization method was benchmarked on a cold-rolled aluminium sheet.

This study presents an approach to overcome this issue by feeding nickel-based filler wire into the melt pool in welding of 2507 super duplex stainless steel. Results showed that the high-frequency beam oscillation combined with a multi-beam technique led a good mixing between the base metal and the filler wire, even at a large depth-to-width ratio. Additionally, the weld geometry was characterized by near-parallel fusion lines and a narrow heat-affected zone. The nickel addition resulted in a balanced microstructure in the weld metal with ferrite fractions of 35–55 %, despite a significant nitrogen loss, consequently leading to impact energy values of 215 ± 15 J and hardness values of 285 ± 15 HV. The findings of this investigation allow fabricators to effectively design electron beam welding processes for producing thick-walled super duplex stainless steel components.
