Future of Laser Welding in Industrial Heavy
Applications- SURESH INDU LASERS
N
ow a days, Laser technology is widely used for
welding of any materials. The fiber laser technology
with stable high-power lasers from 4KW to 10KW has
opened gate for the applications in thick metal welding of
Stainless Steel (SS) & Mild Steel (MS). Even Aluminum welding
having applications in battery can be done successfully using
laser technology. In fact, short wavelength laser welding
systems enable us to weld the materials of more thickness
than the conventional CO2 laser welding. SIL has successfully
developed applications of seam welding with no filler used
for stainless steel with no porosity in weld material with 4KW
fiber laser. Cut-weld-cut or weld-cut-weld system can be
deigned as per application requirements.
SIL welding machine can weld 10 to 12mm thick metals
with 10KW fiber lasers without filler material. However it is
observed that autogenously weld require no or minimal gap
between the two plates. If gap is uneven or more, the energy
passes through the gap without heating the material. With
this limitation comes a welding GTAW process or GMAW
process with laser assisted welding.
SIL has developed systems that can weld thick materials,
alloys & mild steel of 10 to 15mm of thickness. Introducing
the filler material into the weld area & laser acting as a
support to the weld pool make the welding process faster
and smoother with minimal adjacent heated area. So for the
applications that would require ten passes on weld tube, can
be done with maximum of one pass or two pass welding.
Hybrid welding technology can be adapted to the areas of
Ship Building, Tank & Pressure vessels, Marine Structures,
Pipeline and Hydraulic Power Plant with technical expertise
and application lab.
SIL is leading manufacturer of Laser based systems established
in India since 1990, headed & guided by an Indian Laser
Technologist Dr. S.T. Shah who has worked in laser field since
1975, and worked as Scientist at Imperial College of science
& Technology and Liverpool University London for five years.
He has also presented papers in international conferences.
Presently it has six branches in India. We consistently
innovate and develope cost efficient, reliable products with
high precision, based on laser technology incorporated with
robotics for strong International & National commercial
market for applications such as cutting, welding, marking,
engraving etc. SIL is also developing machine for new
applications in their R&D lab for the niche industrial market to
serve India and World around with best quality and minimum
cost to be adaptable in industrial applications.
