Elucidation of laser welding phenomena and factors affecting weld penetration and welding defects
Physics Procedia, 2010 AbstractThe behavior and effect of a plasma plume on the weld penetration are greatly different between CO2 laser welding and YAG, disk or fiber laser welding. The effects of the power and the power density on the weld penetration are elucidated. Spattering leading to the formation of underfilled weld beads is controlled by inclining the laser beam ...

Prediction of Penetration in Welded Joints by Welding Conditions (Part I)
Journal of the Japan Welding Society, 1955 Penetrations of bead-on specimens (200×200 mm, 6, 10, 15 and 20 mm thick) of plain carbon steel were measured for, various welding conditions. (see Fig. 1 and Table 1).Penetration and bead width were presumed by theoretical calculation of temperature distribution near the weld. (see Fig. 2). These are shown-in Figs.
