Laser Texturing to Prepare Metal for Bonding
Technical Papers
Good surface preparation is essential to guarantee good bonding quality. Several surface treatments exist to prepare surfaces. Some of them remove contaminants, some of them modify the roughness level, and others do both, like laser texturing.
Sand Marking Applications
Technical Papers
Laser marking can be used to engrave serial numbers, text, and logos on sand molds used for metal casting. This process is known as sand marking.
Laser Welding Applications for Batteries
Technical Papers
When it comes to making interconnections in the battery module, laser welding is faster than traditional wire bonding methods. With laser technology, the busbar can be welded directly to the cells instead of connected via wires, diminishing by half the number of welds in the module.
Laser Texturing Applications for Batteries
Technical Papers
Laser texturing significantly improves the bond strength compared to mechanical surface preparation techniques. It can also generate a roughness that increases the effective surface area of metal surfaces to improve thermal transfer.
Laser Marking Applications for Batteries
Technical Papers
There are hundreds of battery cells, modules, and other parts in the battery pack that need to be identified for traceability. Laser marking is an outstanding method to create permanent identifiers at a high speed.
Laser Cleaning Applications for Batteries
Technical Papers
Laser cleaning is extremely useful for battery parts that require surface preparation. It improves bonding performance, electrical contact, and welding quality.
Deep Laser Engraving Performance on Metal Surfaces
Technical Papers
This technical paper reports the deep engraving speeds and surface finishes obtained during tests performed by Laserax using the LXQ-HP laser system. Measurements were taken for typical engraving depths on steel and aluminum, and this, at different power levels
Laser Cleaning for Welding Applications
Technical Papers
This technical paper reviews the benefits of implementing laser cleaning before and after welding applications. It also provides cleaning speeds for the Laserax LXQ-HP laser systems to show that laser cleaning can be integrated in production lines without affecting the production output.
Laser Texturing Performance for Metal Surfaces
Technical Papers
This technical paper reports the texturing speeds obtained at different power levels for typical levels of surface roughness required for metals like steel and aluminum.
Laser Marking Performance for Aluminum
Technical Papers
