Technology Update
45 March/April 2007
The TSSS systems – built using IGBT
technology – are available with 5-50kW
induction power supplies, running in a
40-60KHz frequency range. These systems
are ideal for soldering, brazing, heat
treating, annealing and hardening large
components, including ferrous and non-
ferrous alloys. The remote head allows for
bench-top applications and full automation.
ISO 9001 and Vision 2000 certified, Seit
Elettronica considers quality as its main aim.
For this reason, it has developed a quality
system that involves all company functions,
from the planning to the production and
marketing.

Latest range of
tubular brazing wires
FSH Welding Group, France, have
launched a new range of eight tubular
brazing wires. The range consists of an
aluminium tubular wire (TBW Harasil NC
12) for joining aluminium and aluminium
alloys; two zinc tubular wires (TBW Zinal4
and Zinal30NCS) for joining aluminium,
stainless steels and other alloys; and six
silver wires (TBW2040 with cadmium,
TBW5034, TBW5038, TBW5040, TBW5045
and TBW5056 without cadmium) for silver
brazing and silver braze-welding.
The products are made from seamless
tubular wire, which ensures a consistent flux
to wire ratio and requires less flux. Labour
costs are reduced, because no flux has to
be applied separately, the quality of joints
is improved, and no post-braze cleaning is
required, reducing water contamination.
The wires have been designed for use
in both manual and automatic brazing
applications. These include steel and copper
piping, reparation and maintenance on
treated steels, automotive production and
repair, electrical household goods, heating
and ventilation, refrigeration installation and
repair, and precision brazing and medical/
optical applications.
For manual operation, the wires are
available in diameters ranging from 1.5mm
to 6mm, in 500mm lengths, in 5kg packets.
Advantages include no manual contact
between the operator and the flux, less
required heat input compared with solid
wires, and reduced fumes.
For automatic use, the wires are available
from 1.6mm to 3mm diameter, on 0.5kg to
7kg spools.
The latest tubular technology and a
uniform diameter allow consistent feeding
on available wire feed systems and, being
seamless, no problems will occur when in
contact with the drive rollers. The user can
regulate the amount of flux being used
through the wire feed speed to meet the
requirements of the application.
Westbrook Welding Alloys Ltd is the sole
UK distributor for this new range of brazing
wires.
