Welding lathes
MAVRIX Welding Automation Inc has launched horizontal
and vertical welding lathes featuring PLC-based controls.
The straightforward terminology of the PLC reduces the
learning curve, so operators are quickly ready to weld.
With adaptive spindle speed compensation, operators do
not need to adjust wire-feed speed or spindle speed to
accommodate any change in diameter, and dual-axis step
allows for any combination of surface angle. The Mavrix
multi-process horizontal lathe is capable of sub arc, open arc
and gas-shielded welding processes using a single torch.
An on-board second torch is ready for quick changeover for
ID bore welding down to 4" ID. Target customers include
those who remanufacture slab caster rolls, shell rolls, zinc
pot rolls and mandrel bars, as well as other roll options.

Small bore coils
A NEW heat exchanger manufacturing process from Power
Fin Technologies makes prototyping and small to medium
batch production of small bore coils easy and affordable.
The Infinity machine can produce a coil of any two similar
or differing materials using round or elliptical tubes. The
process swages multiple fins into position on tubes as small
as 3mm diameter. This mechanical bond requires no heat,
expansion or lubrication. The work occurs on the outside
of the tube, causing no deformation of the base tube –
imperative when tubes have an enhanced inner surface.
In HVAC applications, price, compactness, light weight,
thermal efficiency, high pressure, reduced coolant or
refrigerant, strength, recyclability and corrosion resistance
are all features of aluminium small bore coils that can create
benefits for manufacturers and end users.
Power FinTechnologies commented that two all-aluminium
coils created great interest when displayed on the booth of
aluminium tube manufacturer Sapa, at the Chillventa 2014
exhibition in Nuremberg, Germany. One was made using a
5mm round tube, while the other was made using elliptical
tube with enhanced internals. Both were made on the same
Power Fin Infinity machine.
The company’s ability to fin elliptical tubes reduces air-
side pressure drop, while the smaller internal capacity
relative to the equivalent circumference of round tubes
improves heat transfer. Small bore stainless steel heat
exchangers, suitable for use in fuel cell or heat pump
applications, can also be made on the same Infinity
machine, as can coils using, but not limited to, copper or
titanium.
A complete fin line system from Power Fin Technologies
includes a de-coiler, press, tooling, guillotine and Infinity
machine. The Infinity machine is also available separately.
