Laser Systems have been used for metal welding for a number of years. They are capable of most weld geometry types and have many advantages over conventional welding techniques.
A more recent application for Laser Processing Lasers is Brazing and Soldering. The Automotive and Electronics sectors have embraced Laser Brazing and Soldering.
Lasers used for welding, brazing and soldering are present in many industries including Aviation, Automotive, General Fabrication, Consumer Goods, etc.
Some of the advantages of using Lasers for Welding, Brazing and Soldering include:
High Process Speeds
Excellent Joint Quality and Strength
Less Post Processing Required
High Surface Finishes
Excellent Process Control and Stability
The laser beam of fiber-coupled LDF diode lasers is transported to the work piece through a fiber. Dependent on the power of the laser the core diameter of this fiber is 400, 600 or 1000 µm. The numerical aperture of the fiber is NA= 0.22.
