Welded joints characterization of UNS N06626 alloy components manufactured using Direct Metal Laser Sintering (DMLS)

This article summarizes the test results ofGTA welded joints characterization conducted by IIS between semi-finished products obtained by Direct Metal Laser Sintering (DMLS) andNi-Cr-Nb UNS N06626 rolled alloy. The growing circulation of these innovative manufacturing technologies and the high interest in some industrial sectors leads inevitably to understanding the properties of these semi-finished products: Among these properties, there is no doubt that weld- Ability plays a major role, in consideration of their different metallurgical and microstructural characteristics. Non-destructive testing and destructive testing were conducted on the welded test pieces, in comparison with the parent material, to get useful elements for the jonts charac-terization and for their in service performances.
