Air When heated up to 30*000 F Undergoes ionic changes & reaches the fourth state of matter, called plasma. Instead for expensive Argon or Nitrogen onl;y compressesd air is used. Hence called Air Plasma.Air Plasma can be used to cut following matels: Mild steel Stainless steel carbon and Alloy steel Aluminium and its alloys Copper Casting Bronze Brass Maganses steel and special alloys etc.Soft Switching Start: Starting current for the Plasma machine is very low. It is safe for the operator and it also enhance the life of the plasma consunmables due to low pilot ARC current, Ideally suitable for machinised CNC Cutting Application.

Even on low current the ARC is stable and is concentrated on the work piece using a constricting Nozzle.The basic difference is in the formation of the ARC.In TIG Welding, the ARC is intiated between Tungsten Electrode and Job, in the presence of inert gas.Ref. Fig. (A).In PAW, the ARC is intiated Electrode and Nozzle in the presence of plasma gas and it is know as pilotARC. Ref., Fig (B).
The Main Plasma ARC is tranfferd to the Job thiough the orifies of the nozzles which constrict the Arc. The Plasma Arc comes out of the nozzles with high velocity ( The Speed of sound), achieving the temperature iof 20, 000 C.

Features of Micro Plasma Welding
* Concentrated Welding Arc, Using low heat current.
* Great Arc Energy.
* Exellent Arc stablity.
* Produce longer Arc length.
* UP slpoes, Down slope, Peak Current & Based Current Features enhance the welding quality.

Gases of Micro Plasma Welding
* Plasma Gas : It gets ionised and flow through the orifice of nozzle.
* Shielding Gas : It flow through outer nozzle and shield and welding, from atmosphere.

History
In 1965, the first Laser cutting machine was manufactured by M/s. Western Electric Engineering Research Center, It used to drill holls in diamond dies.

In 1967, the British harnessed the Laser with the help of Co2 for Metal cutting. In early 1970 this process was used to cut Titanium for aerospace application.


Process
Laser beam is generated by simulating a lasing material by electric discharge or lamps within a closed container. As the lasing material is stimulated, the beam is reflected internally by means of partial mirror, until it archives sufficient energy to escape as a stream of coherent light.

The parallel rays of coherent light from the Laser source often fall in the range between (1.5-2.0 mm) in diameter. This beam is focused and intensified by a lense or a mirror to a very small spot (0.025 mm) to create a very intense Laser beam.

Mirror or fibre optics are used to direct the coherent light to lense, which focuses the light at work zone will the help of different lenses and finally to output Mirror.

Solid State YAG Laser
A Laser is a device that creates and amplifies a narrow intense beam from coherent Light. This light beam is very intense to vaporize the hardest and the most resistant material.

In solid state Laser the active medium is a solid material instead of gas or liquid. The Laser medium is a rod of Yttrium Aluminium Garnet (YAG).

Features of YAG Laser Cutting Machine
* Solid YAG laser medium is one of the most stable product in Laser field.
* It has the features of better Laser mode and thin Cutting Gap.
* It is very stable machine with very little periodical maintaince, except changing of Mirror, lenses and Cutting nozzle.
* It gives high accuracy and high quality of cutting.
* The Servo motors, ball screws, and linear guide rails which are imported not only ensure the good cutting speed, better edge effect, and higher accuracy than similar products, but also ensure the stability and reliability of the machines working.
* No distortion, negligible thermal input, no secondary operation required.

Application of YAG Laser Cutting Machine
Used for precision cutting of Mild Steel, Stainless Steel, Alloy Steel, Spring Steel, Copper and other metals.

Widely used for Aerospace, Steamships, Railways, Wagon, Automobile, Textile machinery parts, Elevators, Kitchenware machinery, Electrical parts, Hardware etc.

Comparison with Co2 Laser
* YAG is specially designed for Metal cutting, where as Co2 is for Metal as well as for non metal like Acrylic, MDF, Wood etc
* Operation cost of YAG Laser is just 1/5 to 1/7 times, compare to Co2 Laser cutting machine.
*Maintenance cost of YAG Laser is 1/10 to 1/15 times, compare to Co2 Laser cutting machine.

Advantages of Laser Cutting Over CNC Plasma Cutting
* No Warping even on lower thickness.
* Cutting is very precised, as minium line width of Laser beam is 0.2 mm.
* No Contamination on the cutting edge.
* No heat effect zone.
* Laser cutting require less energy for sheet metal cutting.
* It can cut hole of as low as 2 mm in diameter
