Group offers a special service in remote mode called teleservice. This allows the company’s technicians to directly access the welding unit installed at the customer’s plant. Website : www.saetgroup.com

The company’s wide range of tube mills offers the latest features including quick change mechanisms, helical gear boxes for distribution of high efficiency power, oscillating type OD based cutting tools, inline straighteners (19 roll), and SG cast stands for excellent damping properties. An online stretch-reducing mill is available for small diameter tubes. Gallium can also supply double mandrel uncoilers, shear and welders, horizontal accumulators, end facing machines, tube push pointers, draw benches and tube straightening machines. The company has supplied equipment to 29 countries including USA, UK, Japan, Australia, Brazil, Iran, Egypt, Malaysia, China, Taiwan, Thailand, Oman, Jordan, Zimbabwe, and Pakistan. Website : www.galliumindia.com Grind Master, India, is the manufacturer of a wide range of machines for metal finishing. Established in 1984, the company exports its machines through MK International, and is committed to providing complete solutions, including tools, machines and processes. The company manufactures a range of centreless machines, including LMCL models with fixed vertical belt heads, used by furniture manufacturers and fabricators of railing and balustrade. Grind Master also produces the sophisticated FH series, used by makers of stainless steel tube, hard chrome bar and hydraulic cylinder. Various models are offered, from heavy grinding high stock removal applications to super finishing applications to achieve 0.05 micron Ra. The machines are modular and configured to suit individual requirements. The design of the pneumatically floating type belt grinding head ensures uniform grinding pressure, even on bent tubes. Advanced features, such as automatic tube size setting and auto wheel wear compensation, make the machines highly user-friendly and process-controlled, ensuring consistency in finishing results.

Emmedi (Saet Group) Italy 10-E105

At Boru 2009, Emmedi (a division of the Saet Group) will present its new 250kW output solid state welder, based on a Mosfet inverter up to 450kHz. The new welder is composed of units including transformer, power supply, welding head, cooling system and control desk. The power supply is a three-phase full bridge thyristor rectifier. Proper filters are inserted in order to reduce the harmonic components that may affect the welding process. Included in this unit is a system control board communicating with the inverter through optical fibres. The inverter is a current fed type, composed of a number of modules (each power rated at 25kW) connected in parallel: the output oscillating circuit is directly connected to the inverter. The correct protection (hardware and software) has been implemented both on the single module and on the whole system to limit component failures. The modular structure and complete diagnosis system allows quick and easy maintenance in order to reduce production stops. A special digital control system has been developed for optimum phase locking (and for an efficiency increase) with the possibility to follow the change of frequency due to load variation, at any working condition. For a quick and cheap solution in case of technical problems and for a reduction of possible onsite intervention, Saet
