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.
