2. What is Laser
 LASER stands for Light Amplified Stimulated
Emission of Radiation
 Laser is a device which generates or amplifies
light
 Stimulated emission of electromagnetic radiation
 Coherent, monochromatic, directional and high
power laser beam is used

3. Laser Beam Machining
 In this process LASER is focused on work
piece by optical lence.
 Used light energy from a laser to
remove material by vaporization
 Energy is concentrated optically
 Thermal and Optical energy is used in
this process
 Light beam pulsed so that the released
energy results in an impulse against the
work surface, producing evaporation
and melting

4. Operation: Laser Cutting
 Cutting starts by drilling a hole by
moving beam
 Cutting speed depends on material
and thickness
 Both pulsed and continuous laser is
used
 Thickness ranges from 0.5-1 inch
 Used for cutting complex geometry
and for clean cutting operation

5. Laser Welding
 For welding ceramics and dissimilar materials like
steel and aluminum
 Produces maximum penetration and minimum
distortion in materials
 Beam can be easily shaped, focused and
directed
 Application
 Razor Blade
 Electronic Circuit

6. Laser Cladding
 Used to improve surface quality by
applying a corrosion resistant layer on
product
 Laser Beam is used to create a shallow
melt pool
 Metal powder is supply using an inert
gas flow
 Application
 Chemical industry
 Mining and marine application
