Straightening, cutting & welding
Advantages of
ultrasonic welding
Ultrasonic welding is said to offer important advantages to manufacturers. It creates
solid-state metallurgical bonds without the need for filler metal materials or for clipping,
soldering, crimping, or dipping. The welding process is also accomplished without
producing arcs, sparks, or fumes and without melting wires.
The Dual Head SpliceRite™ ultrasonic wire splicer – like other Sonobond Ultrasonics
metal spot welders – utilises the patented Wedge-Reed system. This system combines
high vibratory force with
low amplitude coupling.
During the welding pro-
cess, the unit directs
high frequency ultrasonic
energy via the welding tip
to the surface between
the metals to be bonded.
The vibratory energy
disperses the oxides and
surface films, creating a
true metallurgical weld.
There is no melting of
materials. In addition to
creating a very reliable
bond, the process is
environmentally friendly,
produces no waste,
and consumes minimal
energy.
True to its name, the Dual
Head SpliceRite has two welding heads, one on each side of the weld area. As a result,
larger wire bundles – those up to 100mm2– can be spliced in just one quick step. This is
true even when wires are tinned or heavily oxidised. The resulting welds have excellent
conductivity. In addition, the unit has a 3,500-watt power supply and a microprocessor
controller that can store and recall up to 250 jobs. Welds can be controlled by height,
by energy or by time.
All Sonobond metal spot welders feature heat-treated, tool steel taper lock tips.
These tips can last for 100,000 welds or more. They are designed for quick tooling
changes and foolproof placement. Sonobond units also have an important advantage
in that they require only minimal training, being easy to operate.

Flying shear straighten
and cut machinery
In 2002 Videx launched its first paten-
ted servo-operated straighten and cut
machine, which enabled cutting of both
short and long parts at high speeds
without clutches or hydraulics.
Following the success and the improved
reliability of this line, Videx is now
launching its flying shear straightening
and cut-off machine with the same
patented servo-drive. Servo machines
are quieter and more reliable, need less
floor space and allow higher cut-off
rates. The wire speed and cut-off rate
are programmed on an HMI screen that
stores the data and displays all possible
interface and fault messages.
The VC-MSR machines are fully
mechanical, combining the advantages
of the reliable mechanical cut with the
benefits of the servo-drive that replaces
the traditional clutch used by other
machines.
The run-off guide is made from stainless
steel, requiring no adjustment when
changing wire diameters within the
machine range. The gate of the run-off
guide is pneumatically operated, and
supports the wire during cut-off to assure
a square cut face.
The wire transmits the cut-off signal,
just before it hits the positive stop.
The positive stop itself is mounted on
a carriage that rides along the run-off
guide. When the flag “feels” the wire, it
actuates the cut-off cam to cut the wire
and return to rest until the next time
the wire hits the positive stop.
The VC machines are offered with an
integral chamfer station that can chamfer,
face and turn the bars after chamfering.

Straightening solution
Condoroil Chemical has recently developed a new product for the straightening of steel
and stainless steel bars.
The product, named Condorlube S 300, is water-based and free of hydrocarbon solvents
or mineral oil. The straightened surface appears clean, dry and protected for in-house
storage.
Condorlube S 300 straightening solution can be continuously purified and regenerated
using the Athena unit supplied by Condoroil Chemical’s sister company, Condoroil
Impianti.
