INDUSTRIAL induction specialist EFD
Induction has reported strong global demand
for its Weldac induction welding systems.
According to Peter Runeborg the first
two quarters of 2010 saw orders come
in from around the globe: “We’ve had
sudden upticks in demand before. But
what distinguishes this recovery is the high
proportion of retrofits. Approximately 50
per cent of the orders are from customers
wanting to replace vacuum tube welders
with our solid-state Weldacs.”
The shift to Weldacs is driven, says Mr
Runeborg, by the tube and pipe industry’s
tough competitive climate. “To thrive in
this industry producers must maximise
throughput while simultaneously minimising
power consumption and scrap. TheWeldac’s
proven reliability – based on rugged IGBT
transistors – and a constant power factor of
0.95 at all power levels, mean our customers
can boost output while cutting costs.”
The Weldac also features electronic
matching, which helps ensure maximum
welding speed for the entire product range.
The system automatically matches to the
optimum setting when a new workpiece
size is introduced, when there is a change
in mill set-up, or when a differently sized
coil is fitted.
Weldac’s compact footprint and easy
integration are other factors behind the
increase in retrofitting orders. “Weldacs
up to 600kW are housed in a single
cabinet,” said Mr Runeborg. “This feature
makes retrofitting quick and easy. In fact,
retrofitting a single-cabinet Weldac system
typically takes less than a weekend. The
benefits are minimised downtime and
installation costs.”
EFD Induction has manufacturing plants,
workshops and service centres in the
Americas, Europe and Asia, and corporate
headquarters in Norway.
