Operando X-Ray Tomoscopy of Laser Beam Welding. [PDF]
Adv Sci (Weinh)AbstractThe phenomena occurring in a weld seam during advancement of a laser beam over a metallic component are still under dispute. The occurrence and evolution of porosity and the occasional blowout of melt need to be understood. Here, a recently developed X‐ray tomoscopy setup is applied, providing one hundred 3D images per second to capture the ...
