able to retrofit their corrugated line with this new technology. The SheathEx process provides a continuous and seamless aluminium sheath with no weld. The aluminium sheath has good conductivity and environmental properties and is light in weight. The use of standard CCR aluminium rod keeps material costs low. BWE continues to develop new products and applications, including wire arc additive manufacturing (WAAM), 3D printing, electric vehicles and precious metals. Proving trials and demonstrations are available at BWE’s headquarters in Ashford, Kent, UK. The company’s research and development department will consider and prove any new application prior to investment. BWE also manufactures and supplies a complete range of cold welders and dies for a fast and reliable solution to welding non-ferrous materials from fine wire to round rod. A range of machines will be on display and available for demonstration.

Conklad technology is available for applications such as AS wire, OPGW, CATV, sheathed composite cores, reinforced aluminium wire and other products requiring an aluminium sheath or non-ferrous cladding. BWE’s SheathEx™ technology was first developed in 2005. The process is used for ‘seamless’ aluminium sheathing of high voltage cables. Until now, all machines supplied globally have been for a corrugated aluminium sheath – a reliable process from 2 x 12mm diameter aluminium rods. BWE now offers a SheathEx line for both a corrugated and smooth

BWE LTD is a British engineering company specialising in continuous extrusion machines and cold pressure welders. Its Conform™ and Conklad™ continuous extrusion technologies are established in the non-ferrous, cable and tube industries. Typical applications for Conform include copper and aluminium rectangular wire (magnet wire for transformers), solid aluminium conductor (SAC for cables), copper busbar, trolley wire and other shaped conductors, round refrigeration tube and multiport or PFC tubes in different alloys.

aluminium sheath. One of the first SheathEx customers worked with BWE to develop and convert its line for both corrugated and smooth. Extensive tests in tandem with the plastic extruder allowed the cable to bend and wind on a drum without kinking or damaging the sheath. Existing customers are

solution for hot-rolled long products using a high-performance eddy current system; and MASSdiscover is used for continuous measurement of mass flow in hot-rolled products and real-time calculation of equivalent cross section. ISEND designs, develops and installs NDT solutions for surface inspection and process control of 100 per cent of the production of metallic products. The solutions include proprietary eddy current technology, computer vision and AI, positioning the company to take advantage of Industry 4.0, “big data” and IoT. The company develops solutions for the inspection of wire rod, hot-rolled bar and cold products, allowing detection of point, transverse and longitudinal

ISEND produces solutions for rolling mills: non-destructive testing (NDT) with eddy current, machine vision and artificial intelligence and mass flow control. EDDYeyes is an NDT solution for hot-rolled and cold-processed long products, featuring defect detection by eddy current, real-time image capture and automatic identification and classification of defects using machine learning and AI. The system facilitates 100 per cent production quality assurance and decision making. It predicts the appearance of systematic defects and optimises surface quality analysis, providing accurate location of defect positions and their images. The company’s HOTdiscover is an NDT
