Technology Update

The TSSS systems – built using IGBT technology – are available with 5-50kW induction power supplies, running in a 40-60KHz frequency range. These systems are ideal for soldering, brazing, heat treating, annealing and hardening large components, including ferrous and non- ferrous alloys. The remote head allows for bench-top applications and full automation. ISO 9001 and Vision 2000 certified, Seit Elettronica considers quality as its main aim. For this reason, it has developed a quality system that involves all company functions, from the planning to the production and marketing.

aluminium tubular wire (TBW Harasil NC 12) for joining aluminium and aluminium alloys; two zinc tubular wires (TBW Zinal4 and Zinal30NCS) for joining aluminium, stainless steels and other alloys; and six silver wires (TBW2040 with cadmium, TBW5034, TBW5038, TBW5040, TBW5045 and TBW5056 without cadmium) for silver brazing and silver braze-welding. The products are made from seamless tubular wire, which ensures a consistent flux to wire ratio and requires less flux. Labour costs are reduced, because no flux has to be applied separately, the quality of joints is improved, and no post-braze cleaning is required, reducing water contamination. The wires have been designed for use in both manual and automatic brazing applications. These include steel and copper piping, reparation and maintenance on treated steels, automotive production and repair, electrical household goods, heating and ventilation, refrigeration installation and repair, and precision brazing and medical/ optical applications. For manual operation, the wires are available in diameters ranging from 1.5mm

to 6mm, in 500mm lengths, in 5kg packets. Advantages include no manual contact between the operator and the flux, less required heat input compared with solid wires, and reduced fumes. For automatic use, the wires are available from 1.6mm to 3mm diameter, on 0.5kg to 7kg spools. The latest tubular technology and a uniform diameter allow consistent feeding on available wire feed systems and, being seamless, no problems will occur when in contact with the drive rollers. The user can regulate the amount of flux being used through the wire feed speed to meet the requirements of the application. Westbrook Welding Alloys Ltd is the sole UK distributor for this new range of brazing wires.
