No splash welding, we're serious!

In recent years, optical fiber lasers have been widely used in the field of metal welding and cutting, but in some welding applications, there are still unsatisfactory results, such as, when welding, it is easy to spatter.

What's the impact of the splash?
After laser welding is completed, there are many metal particles on the surface of the material or workpiece, which are attached to the surface of the material or workpiece. This is the particle produced by splashing. These particles not only easily scratch the base material, contaminate the protective mirror of the welding helmet, and contaminate the filter of the camera of the equipment and the glass sheet, resulting in rework of the components, damage to the components, and even more serious will lead to shutdown.
In particular, the automotive industry needs a large number of welding of specific materials such as galvanized steel plates, copper and aluminum. In the past, the way to eliminate splashing was to greatly reduce the processing capacity and efficiency by sacrificing the inherent advantages of fiber lasers.
Until it appears ...

Spatter welding weapon
YLS-6000 / 9000-AMB beam mode adjustable fiber laser
Technical principles
AMB beam
Small spot high energy high brightness center beam and larger ring beam arbitrary combination
Ordinary laser welding spatter
The laser continuously acts on the material, causing the material to vaporize and expand to generate pressure and form a molten material.
High pressure is generated when metal steam escapes, pushing the material towards the top of the spoon hole.
The spatter is pushed out of the top of the keyhole and attached to the surface to form a melt
AMB laser welding splash small
AMB can produce a larger and more stable spoon, making it easier for metal vapor to escape; The circular beam minimizes the steam kinetic energy of the escape, thereby minimizing splashing.
On the other hand, AMB can make the melt pool more stable and no further melting occurs after forming a more stable spoon hole. The circular beam softens the material and deflects towards the bottom of the pool, thereby significantly reducing the splash.

Industry application cases
Minimum splash welding of copper
Ordinary high splash welding AMB less splash welding
Process: 3 mm joint weld
Materials: 0.2 mm nickel plating copper + 0.2 mm nickel plating copper + 2.0 mm copper
Welding speed = 120 mm/s
Minimum splash welding of aluminum
Ordinary high splash welding AMB less splash welding
3Mm splice weld
Material: 0.2 mm aluminum + 0.2 mm aluminum + 2.0 mm nickel plating copper
Welding speed = 45 mm/s
Adjustable beam mode to achieve minimal splash
The car manufacturer has benefited greatly.
For the traditional car manufacturing advantage
Increase welding speed of auto parts
Reduction of porosity and zero gap welding of galvanized steel plates
Eliminate controlled gaps that may increase additional costs
Improvement of post-weld mechanical properties of rough materials
Low splash reduces surface roughness and improves formability
No splash welding, we're serious!
