The OSLW Application
Optimization Software for Laser Welding
The OSLW model is a specialized application for analyzing continuous wave laser welding in the conduction and keyhole mode. OSLW is helpful in developing weld procedures with optimized energy transfer and reduced heat input. It is based on an empirically developed dimensionless parameter model that is applicable to all metals and alloys.
OSLW incorporates a weld penetration model that is dependent on the laser beam intensity, travel speed, focused spotsize, and the shielding gas. The calculated results are therefore specific to the laser type, the beam quality, and the focusing lens used.OSLW enables the user to:
OSLW GUI is divided into an output weld procedure listing, plot selection
window, weld specification window, and a graphical weld cross-section
display. The output listing contains the computed weld procedure and associated
responses from the optimization. The plot selection window provides several
types of graphics for more advanced analysis. The weld specification window
accepts inputs for alloy type, a preferred focusing lens, desired weld
depth and width, and the type of optimization desired. The program will
often return different weld procedures depending on which efficiency is
to be optimized. Completion of the weld procedure computation results
in updated weld shape and analysis graphics displays. 2-D and 3-D analysis
plots display the entire penetration depth contour of which the computed
weld procedure is but one point. This allows the user to do tradeoffs
if a neighboring suboptimal solution is considered preferable for the
