The YAG model is a specialized application for analyzing overlapping
spot, pulsed Nd:YAG laser welding of 304L stainless steel cardiac
pacemaker batteries. YAG was developed to lower peak temperatures
near glass-to-metal seals.
YAG is an example of SmartWeld's versatility. Quite different from other
SmartWeld applications, YAG is based on designed response surface experiments
used to compare laser welding performance with different focusing
In addition to reducing heat input, YAG also allows the user to determine
the effect of laser process parameters on weld dimensions.
YAG displays the assumed weld shape as it is changed by the user.
YAG enables continuous weld model output via "mouse-down" button clicks
on the 2-D contour plots.
The application is not a general purpose model for pulse laser welding
of other materials and thicknesses. Other SmartWeld applications should be
considered for those more general weld problems.
