AT this year’s Schweissen & Schneiden trade
fair for joining, cutting and surface coating
(14-19 September), automated TIG welding
expert Polysoude, France, will show its newly
developed systems, machines, components
and solutions for orbital and mechanised
joining and cladding.
The market launch of the P6 300-ampere
mobile TIG welding system, for tube
assembly using automated orbital welding,
opens up new production possibilities
for plant construction – technologically,
economically and qualitatively, the
company claims.
It says this is made possible by more
intuitive operation combined with the
modular system concept – features shared
with the smaller P4 version. A large touch
screen provides the interface through
which all interactions with the system
take place. This touch screen issues all
commands to the internal electronics via
the software and transmits the status of the
joining process to the operator.
Other special features of the P6 are
autonomous system configuration and
auto-programming. The P6 also features
real-time welding data recording for
reproducible welding results. The machine
not only detects the type of tool connected
(open or enclosed weld heads) but it also
knows within which limit values the tool can
work. Auto-programming takes over the
adjustment of the welding parameters down
to the last detail.
Along with the precision power source, the
weld heads are the most important factor in
the joining system when using automated
orbital welding.
Visitors can expect significant new develop-
ments with open and closed weld heads:
more compact with smaller dimensions and
lower weight; and easier to use with quick
clamping systems that are independent of
the tube diameter.
For wear-resistant finishing to the inside
and outside walls of tubes and components,
Polysoude has developed a system for TIG
hot wire surface cladding. The company
also produces mechanised and automated
joining solutions for a number of other
branches. Its engineers have developed
a special automated joining technology
for boiler construction in power plants:
TIG narrow gap welding. This process is
especially suitable for joining thick-walled,
concentric circular work pieces. The joining
technique is suited to wall thicknesses
between 25 and 300mm.
