Eliminate the guesswork and operator
variability by switching to laser welding at Directed
Light. All our laser welding systems have 3 or
4 axes of CNC motion control to ensure accurate,
repeatable joints. Laser welding minimizes the
heat-affected zone to prevent damage to packaged
components or to the material surrounding the
weld. Through laser process selection and tight
production control you will see a constant weld
depth and overlap part after part after part.
Directed Light has systems for laser
spot welding and laser contour seam welding. We
weld under a shield gas or can use one of our
glovebox systems to bake and weld packages in
an inert atmosphere.
To optimize your laser welding project’s
success we will share our expertise in weld joint
design and material selection during your design
process. Proper joint design and material selection
will ensure consistent, strong, crack free welds.
While many other combinations of materials can
be welded, using one of the preferred combinations
of welding materials listed below would promote
excellent laser welds.
General- Easy
304 SS – 304 SS (or 304L)
Titanium to Titanium
Carpenter 49- Carpenter 49
Carbon Steel – Carbon Steel (.2%C max.)
|
Hermetically sealed packages
4047 Al lids to 6061 Al packages
Kovar lids to 304 SS packages

Moderate: Joint design and welding parameters
are more critical for these combinations but they
can still be welded fairly easily.
