Comparison of joining efficiency and residual stresses in laser and laser hybrid welding [PDF]

open access: yes, 2011
Laser welding is a high energy density process, which can produce welds with less energy input and thereby lower residual stress generation compared to arc welding processes.

Review of the Definition of Weld Penetration, Depth of Fusion and Throat Thickness on Fillet Welds

open access: yesGazi University Journal of Science, 2023
In this study, definitions of Weld Penetration (WP), Depth of Fusion (DOF) and Throat Thickness (TT) in fillet welds according to related standards are evaluated. Each standard makes its own definition related to WP, DOF and TT. Moreover, when looking at these standards, it is seen that definitions are always made in terms of unit of length.

Interpreting acoustic emissions to determine the weld depth during laser beam welding

open access: yesJournal of Laser Applications, 2022
The interpretation of sensor system data is critical for monitoring industrial welding processes and providing reliable information about the condition of the weld seam. Previous investigations have shown that acoustic emissions of frequencies up to several kilohertz during laser beam welding are parameter-dependent and contain valuable information ...
