LASER is an acronym for “Light Amplification by the Stimulated Emission of Radiation” which produces a sharp, focused light beam that melts a very small area of metal. The benefit of this technology is that very little heat is generated at the weld point, allowing users to easily weld microns away from the most complicated and intricate component parts without damaging heat sensitive materials.
Micro laser welding is used for joining high value, miniature components in a range of industries such as electronics, telecom, automotive, the medical industry and more. Typical applications include catheters or implants, orthodontic brackets, fiber optic couplings to laser diodes, hermetic seals, watch part components and other photonic fabrication devices. Compared to conventional joining methods, micro laser welding is recognized as a high-speed, repeatable process that offers numerous advantages, including:
High quality weld (smooth seam surface, no oxidation, no part distortion)
Minimum heat-affected zone, which minimizes damage to the work piece. Low heat input: the weld energy is delivered only where it is needed and with exceptional control
Non-contact process with great accessibility of the hard-to-reach welding areas including deep and narrow areas
Simple integration with viewing systems for micro precision material positioning and handling
No need of a vacuum chamber, as required by electron beam welding
Clean welds: In addition to the aesthetic benefits, clean welds result in products that are easier to sterilize or fit into other assemblies
Strong welds: Laser provides high strength with minimum number of welds
Hermetic welds: Unlike soldering or brazing, lasers can provide flawless hermetic welds essential for many micro- applications.
Our state of the art equipment enables us to perform uniform, continuous welding without pigmentation,creating a complete, hermetic weld while upholding supreme precision and avoiding overheating and / or deformation of the welded specimens.
LaserLux's micro laser welding is performed in a protective work environment (Argon cloud), safeguarding against the oxidization of the welded parts while maintaining low working temperatures; thus preventing distortion (deformation / blockage / hardening) amongst other thermal effects.
The laser is an excellent tool for the welding of almost all common metals and their alloys. The wide range of tried and tested applications include stainless steel, gold, silver, platinum and titanium, as well as shape memory alloys.
LaserLux provides the professional capabilities to weld the following metal (amongst others):
Stainless steel and steel – all grades (Austenitic, Martensitic and Ferritic)
Nickel Titanium Titanium Nickel Chromium
Cobalt Chromium Platinum / Platinum Iridium Aluminium
17-4ph / 17-7ph (precipitation hardening metals)
