rod & bar production
As energy and materials costs continue to rise, increasing numbers of wire and cable manufacturers are discovering that cold welding
is an economical and efficient way to bond non-ferrous rod sections.
British company PWM, which has been
at the forefront of cold pressure welding
technology for almost 25 years, has
developed three powerful rod welders to
help manufacturers join rod quickly and
cost-effectively. No heat, flux, filler or fumes
are involved in the cold weld process,
which creates a permanent bond stronger
than the parent material.
The EP500 model, one of PWM’s
best-selling machines, is extremely easy
to use and maintain. Virtually no operator
training is required and the EP500, like all
PWM machines, produces a reliable weld
every time, reducing material wastage.
Capable of welding copper rod from 5mm
to 12.5mm and aluminium from 5mm to
15mm, the EP500 usually only requires
maintenance every three years or so.
PWM’s largest rod welder, the electro/
hydraulic P1500, offers an efficient and
economical method of welding large
copper rod sections up to 25mm in
diameter (aluminium to 35mm). Power
consumption is minimal and the P1500
guarantees a sound bond every time.
The hydraulic P1000 model
is a compact but powerful
machine with a small foot-
print and a wide capacity
ranging from 6mm to 16mm
copper and 6mm to 20mm
aluminium.
Designed with a sloping front
panel and angled mechanism
for ease of operation, the
P1000’s quick release dies and
easily adjustable die setting
ensure that die changeover is
fast and problem-free.
Most non-ferrous metals can
be cold welded as well as
various alloys.
The cold weld process can
also be used to join dis-
similarmaterials, for example,
aluminium to copper, and
materials of different sizes.
PWM’s UK-based specialist
team is always available to
provide advice and support
on rod welding techniques
and applications.
