Indian Laser Association
in collaboration with
Centre for Advanced Technology, Indore
Indian Laser Association is organising an orientation course on
"High Power CO2 lasers and laser Material processing".
Lasers are being increasingly used world wide to process a bewildering
variety of materials in many interesting ways. Laser material
processing techniques including cutting, welding, drilling, marking,
surface treatment, alloying and cladding have considerable potential
in automobile, chemical, nuclear, aerospace, metallurgical and
mechanical engineering industries. As of today, there is a very
limited activity in this field in the Indian industries. One of
the reasons is the lack of awareness and proper information of
this new technology.
Basically laser is an intense source of electro magnetic (EM)
radiation, the two industrial lasers mostly used in material processing;
namely Nd:YAG and CO2 lasers operate in infrared region
of the EM spectrum. When high power laser beam is focused on a
surface, it produces very high power densities in 105
- 107 W /cm2 range. At such high power densities
the material can be melted and evaporated. Controlling the laser
power density and interaction time of laser beam with the work
piece, different processing e.g. cutting, welding, surface transformation
hardening, drilling, alloying and cladding can be realised with
the same laser. The process depends on various laser and process
parameters, and material properties e.g. laser power, beam mode,
laser wavelength, polarisation, temporal modulation, focal spot
size, location of focal spot with respect to work piece, processing
speed, assist and shrouding gas, their pressure and orientation
of flow and thermal diffusivity of material etc.
It is essential to understand effect of these parameters on the
processing to get the desired results. A few industries are using
lasers in their production line, mostly for cutting applications.
However, in absence of any formal training in this field and the
lack of in-depth understanding of the laser processing technology,
the full capability of the laser machine may not be exploited.
This course is designed for executives, supervisors and technologist
already involved in the laser material processing or considering
to adopt this new technology to provide an in-depth understanding
about high power CO2 lasers and various material processing
applications with a special emphasis on laser cutting which shares
more than 80% of all laser material processing applications.
The course is being formulated and will be delivered by CAT scientists
who have long experience in developing high power CO2
lasers and their material processing applications. This will consists
of technical lectures and practical demonstration of various laser
processing.

Indian Laser Association (ILA), in collaboration with Centre for
Advanced Technology, Indore is organising an orientation course
on "High power CO2 lasers and laser material processing"
during Jun.1-5, 1998.
Today in our country only a few industries are using high power
CO2 laser for cutting applications. It is felt that
many more could take advantage of this new promising technology
but lack of proper information and in-depth understanding of laser
processing are the major hurdles. Realizing the need, ILA is organising
a formal course for industries and R&D organisations engaged
/interested in this area.
Centre for Advanced Technology, (CAT) Indore, a premier institute
of the country on high power lasers and applications has kindly
agreed to extend its facilities to organize the course. The course
will consist of technical lectures and practical demonstrations.
The lectures will cover high power industrial lasers and various
material processing applications e.g. cutting, welding, surface
modifications, hardening, alloying and cladding with special emphasis
on CO2 lasers and laser cutting, problem shooting,
maintenance and safety aspects. Practical demo of laser resonator
alignment, laser operation and its optimization, cutting of metallic
and non-metallic sheets, laser welding and cladding will be done.
We are looking forward to you for taking advantage of this opportunity
through your nominations / participation in this course. Please
find enclosed herewith a program announcement brochure and registration
form. We welcome suggestion regarding the course contents.
The last date for receiving registration form along with the course
fee is May 15, 1998.
With kind regards
Yours sincerely,
