“Laser Welding” is a combination of terms using Laser (Light Amplification by Stimulated Emission of Radiation) and Welding(Melting and Fusion of Materials). Light energy is intensified into a concentrated and concentric path(beam) directed onto the surface of two materials- melting and fusing them together.
Why LBW over conventional Welding process such as GTAW/TIG?
1) Low Heat Input = Minimal Distortion.
2) Low Operator Skill Required – Welding with joystick.
3) Low Risk of burns, scalds and work injury.
4) Low Heat Affected Zone (HAZ)
5) Precision Control and Viewing of Weld Pool through Ergonomic Microscope.
6) Able to weld thin materials without blow through.
How do Laser Beam Welding (LBW) Machines or Laser Welders work?
LBW Machines uses a gain medium to excite and intensify the light energy. This beam of amplified energy is then guided to the workpiece by reflecting across delicate mirrors. The diameter of the laser beam can range from 0.2mm to 2.0mm. Aphla Lasers uses a gain medium of either a YAG crystal or Fiber Optic.
Why Laser Beam Welding?
LBW generates a very high peak power while keeping the overall heat input into the workpiece to the minimum. In laymen terms, you can place your fingers onto a 1mm spot weld after welding without feeling any heat. In technical terms, time taken from the melting and solidification of the molten metal is in milliseconds which increases the rate of heat dissipation.
Alpha Laser
has a Micro
Welding Option
Alpha Lasers has a Micro Welding Option, allowing beam diameter to be smaller than 0.2mm. User with basic human motor skills is capable enough to produce a sound weld with Alpha Laser System.
Metal Joining
Fusion of similar / dis-similar metals.
Metal Restoration
By building up on word or damaged surfaces or edges.
Metal Repair
Joining back two broken metals together.
Laser Beam Welding is also often used for seam or seal welding.
