Polysoude publishes
TIG cladding handbook
DURING the Industrie 2012 (Paris) and
Tube and wire 2012 (Düsseldorf) trade
fairs, Polysoude, an expert in TIG/plasma
automated procedures, published the first
handbook for ‘Mechanised TIG Cladding for
Industrial Applications’. The 48-page guide
contains information and an in-depth insight
into the technology and know-how of this
high-potential process. Industrialists will find
helpful information and assistance on the
subject, as well as practical tips and advice
as to the various uses of TIG cladding.
Flexibility, excellent surface quality of
TIG welds, and the possibility to weld in
all positions are determining factors that
have led Polysoude to the automation of
this process in response to the growing
industrial demand.
The main advantages of the TIG process
are that it allows for mastery of the weld
pool in all positions, achieved thanks to
high flexibility in the adjustment of welding
parameters; and the possibility to control
and supply the required amount of energy
accordingly, enabling the respect of the
characteristics of the material and in the
particular case of cladding, to reduce the
surface dilution level using exclusively one
or two successive layers.
Polysoude, with over 50 years’
experience in the field of orbital and
mechanised welding, has accelerated the
development of equipment and
welding operating procedures
for cladding operations using
the TIG process and its variants.
One such variant is the buttering
of the ends of workpieces,
for example in the case of
heterogeneous joints.
Cladding operations that use
the TIG process are widely used
in the repair of high-value added
worn parts in service or following
manufacturing anomalies during
machining; and preventative
cladding operations using materials that
are resistant to mechanical wear and tear,
abrasion and corrosion.
In order to monitor the welding process,
the operator can be assisted by a video
system, exclusive to Polysoude. This
supplementary quality guarantee consists
of cameras mounted close to the torch, or
even integrated in the body of the torch for
more difficult cases, such as limited access
or harsh/extreme environments such as
preheating.

Core competence and innovation
INDIAbelongs to the five biggest producers
as well as to the five largest consumers of
steel in the world, with an estimated growth
of 16 per cent until 2012.
Additionally, planned investments
from the Indian government as well as
major investments by international steel
companies further strengthen India’s steel
industry.
The building and construction industries
along with the oil and gas sector are the
major marketplaces for pipe in India.
With the construction market booming
and further development of new markets
for steel pipes ranging from commercial
framing to water pipes, the future of the
steel tubing industry certainly looks bright.
Rising business opportunities in the Indian
oil and gas sector and the rapid growth
in the Indian petroleum sector call for a
country wide pipeline infrastructure.
The organisers have therefore invited
readers to participate in the 5th edition
of South Asia’s successful business-
to-business platform for the tubes and
pipes and metal industry – Tube India
International 2012/Metallurgy India 2012.
Starting from 2012 the proven trade
fair duo takes place parallel to Wire &
Cable India. Exhibitors and visitors from
all industries will benefit from this triple
constellation.
Invaluable synergies for exhibitors and
visitors are also created by the parallelism
with India Essen Welding & Cutting 2012,
which is held in hall 6, and the conferences,
workshops and seminars which will round
off the events.
Companies can use Tube India
International 2012/Metallurgy India 2012
as a platform to showcase their products,
technology and know-how to the decision
makers of the region and to strengthen
their position in India.
