The Watt Laser SE12 is designed for laser surface engineering like structuring, marking, and welding. It has a travel range of 710 x 790 mm and laser power from 3-100W. The SE12 uses a patented process called Nanoslic to apply a hydrophobic ceramic coating to stencils. It removes contaminants from the surface and increases surface area with millions of micro-rivets, creating the most durable stencil coating. The SE12-W variant can weld metals with 20 micron accuracy to create advanced multi-level stencils, with zero heat distortion and weld strength equal to the original material. It requires no assist gas and uses vacuum and machine learning for distortion-free welding

3. The SE12 is a core part of the new
patented Nanoslic™ hydrophobic
coating process
The Watt Laser SE12 is designed to
remove contaminants and oxides from
the stencil surface AND importantly,
increase the surface area of the
substrate.
This e
ff
ectively provides millions of
micro-rivets of Nanoslic™, gripping to
the surface of the stencil.
This results in the world’s most e
ff
ective
AND the world’s most durable stencil
nano coating.

4. The SE12-W can alter the surface of a material to
melt and weld metals with incredible accuracy. These
welds are placed to within 20 microns to create the
most advanced multilevel stencil in the world.

Unlike other welded steps, the resulting
weld is super flat, having ZERO heat
distortion. The weld is also as strong as
the original material.

5. 1.
No assist gas - Other laser welded Stencils require argon or nitrogen to weld step stencils.
The Watt Laser SE12-W does not.
2.
No heat distortion - The Watt Laser system uses proprietary machine learning algorithms and
vacuum technology to eliminate flatness issues found in other multi level welds.
3. Large vacuum fixture - A 395x395mm precision engineered vacuum fixture for maximum
area and the highest quality. ( e.g. a customer recently did 35 separate welds of various
thicknesses in 1 operation).
4.
Thin material welding is now possible. The SE12-W can weld down to 0.05mm thick
material.
5. High speed - Utilises beam steering optics for much faster welding.
6. Weld out of tension - Perfect for vector guard and other frameless stencil types.
7. Weld larger step increments in one operation - (e.g. 0.07mm to 0.25mm can be welded
directly in one operation).
8. High strength - Focus issues on other laser weld systems can be as a result of poor setup, but
most often from metal buckling under heat distortion, this causes the weld strength to be
compromised.
