the Weldac system has become a proven
solution, boosting welding productivity at
companies worldwide.
Weldac’s reliability is based on a robust
design and solid components. The IGBT
transistor solution makes the Weldac
virtually short-circuit proof, with practically
no ripple.
Weldac is one of five product families from
EFD Induction. Together, these product
families enable the performance of almost
any industrial heating task.

With over 25 years of experience, Elmaksan
is the manufacturer of an extensive
machinery range including pipe and profile
lines, cut-to-length lines, slitting lines, multi
blanking lines, trapeze lines, open profile
lines, slitting knives and spacers.
The company also offers coil process
equipment, automatic packing machines,
levelers, rotary shears, multiple cutting
units and associated spare parts. Each of
these lines can be modified to meet clients’
specific production needs.
Elmaksan operates two large facilities, one
located in Istanbul (5,000m2) and another
in Kocaeli (22,000m2), staffed by over 150
people.
More than 80 per cent of the total volume
of production is exported abroad to 40
different countries all over the world.
With a constantly expanding product range,
the company’s machinery is designed,
manufactured and supplied according to
the highest quality standards.

There are some obvious advantages to
perform a mill setup on the computer rather
than on the mill by practical trials. These
include the possibility to add, edit or remove
any cage station (straight edge forming
system) within the current tube mill roll tool
layout. This is undertaken via the built-in
tool browser where the forming lineal can
be positioned between the existing forming
stations.

EFD Induction is a supplier of industrial heat
solutions based on induction technology.
The company has introduced a patented
solid-state concept that promises to
significantly boost tube-welding output, with
higher efficiency, quality and more uptime.
Weldac solid-state welders come with a
5-year warranty for their inverter modules,
with driver cards included. Since its launch
data M Software is a software specialist
for the rollforming and tube and pipe
manufacturing industry. The company will
present the new version of its finite element
simulation solution for the rollform process
Copra® FEA RF 2009. Copra® FEA RF helps
the manufacturer to understand the rollform
process, trace recurring problems and carry
out target-oriented optimisation.
Due to the fact that rollform technology is
continually developing, data M sees it as
essential to add new possibilities into FEA
software. The company believes that this
new version has come closer to reality
than any other simulation or analysis
software.
The company has enhanced both the FE
Analysis software and also the renowned
design package, Copra® RF. One specific
feature to have been improved is the
handling of cage forming methods.
Copra® CageForming is a straight forming
method that enables the possibility to
design and model any type of rolling cage.
A cage forming system is a continuous
forming process by groups (beams) of
single simple rolls and additional supporting
outer and inner roll tools.
Copra® allows for modelling of various types
of straight edge forming systems due to its
parametric structure. The lineal beams are
either predefined or -– if there are single
mounted rolls – each roll and respective
position is defined in specific database
tables. In order to achieve a correct forming
result it is important to have a smooth strip
entry into the forming cage.
Therefore it is important to optimise both
entry passes as well as the position of
forming and guiding rolls in the forming line.
