Laser weld pool optical diagnostics: Topography and visualization used for surface contour analysis and process monitoring
This experimental investigation into shallow laser welding describes new techniques for visualizing, measuring dimensions, and mapping the deformation of the weld pool free surface. The first known measurements of the molten surface contour have been obtained, analyzed, and compared with predicted …

Characterization of nitrogen effects in high energy density weldments of Nitronic 40 stainless steel
Variation in the welding environment for laser beam welding and electron beam welding can alter the resulting weld chemical composition, microstructure and therefore the mechanical properties. The room temperature mechanical properties of Nitronic 40 stainless steel weld metal from three different …
