EFD Induction develops, commercialises and supplies complete industrial heating processes, including power sources, mechanical handling equipment and control systems based on the latest IT technology. EFD Induction has emerged as a pioneer in finding new induction heating applications and solutions. The Weldac G2 is the company’s family of high-output solid-state welders. It is available with output power of 150-2,000kW and with 100, 200 and 300kHz nominal frequencies. The Weldac uses rugged IGBT transistors, which due to EFD’s patented switching pattern, can now be used in high-frequency applications, such as tube welding. IGBT transistors are virtually short-circuit proof, making the Weldac very reliable and robust equipment that provides more uptime and output. Apart from capitalising on the strengths of standardised IGBT transistors across the entire frequency range, the Weldac G2 system also provides continuous electronic load matching. Continuous electronic load matching secures full power output across a wide range of tube sizes, ensuring maximum welding speed for each size. The Weldac eliminates the need for costly compensation capacitors by using diode rectifiers that result in a high, constant power factor (0.95) at all power levels. Test- verified efficiency from input at the rectifier to output at the coil is 85-87 per cent. Cooling water consumption is low, with no need for expensive de-ionized water.

data M develops software to help engineers optimise tube properties and understand the strains that a tube undergoes as it is manufactured and later fabricated. This knowledge can help engineers reduce the amount of material necessary and also reduce or eliminate annealing, thus lowering energy and material costs.

Bronx/Taylor-Wilson Ltd UK/USA

Stand 5D150

Bronx/Taylor-Wilson is a renowned manufacturer of metal finishing equipment solutions, with over 100 years of industry experience and thousands of installations worldwide. The company’s product portfolio includes tube straightening machines in 6 and 10 roll versions, hydrostatic pipe testing machines, rotary cut-off and end facing equipment, bar section and profile straighteners, material handling and other ancillary finishing equipment. Bronx equipment utilises the latest revision of their highly proven Computer Aided Setting System (COMPASS) which employs the latest in industrial electronic technology to predict optimized roll settings based on operator input. The system provides the user with a consistently high quality product and throughput capacity with the added benefit that size changeover times are now reduced to under 3 minutes.

Involving everyone in the chain – the roll tooling engineer, tube mill operator, and the fabricator – is the key to making the greatest gains in efficiency. The data M Software + Engineering group will present its new version of roll design and process simulation software, branded Copra ® RF and Copra ® FEA RF, which offers enhanced features for the design of roll tooling and the simulation/ verification of the forming process. Copra ® RF now supports the automatic design and analysis of 4-roll fin passes and 5-roll welding passes and avoids user’s manual interaction in these specific cases. It also allows for the design of cage forming/linear forming tooling. In the production of extremely thin walled welded tubes the coil is often drawn to shape rather than roll formed. With the latest version of Copra ® RF, it is also possible to integrate the drawing dies within a roll forming tool set. This allows the analysis of the complete forming process and to predict and optimise the final tube’s properties. › A new feature of Copra ® is the possibility to design and model any type of rolling cage using the software – often referred to as the straight edge forming method
