used in the frame structures. Normek then welded the steel arches from these strips and cuttings with numerous passes to create an artistic result that resembles a large lattice structure. In the final stage of construction, the steel frame will be hidden under wood cladding. The library will have a façade of wood and glass. Designed by Helsinki architect firm ALA Oy, Helsinki Central Library is scheduled for completion in late 2018. When completed, the three-storey building will be a public space. In addition to an extensive range of books, the library will feature a film theatre and extensive recreation, work and exhibition premises. SSAB AB – Sweden on electrodes that have been ground incorrectly. Savings can be achieved because of the increased life of properly ground tungsten electrodes. With a special collet accessory, shorter tungsten electrodes can be held, increasing the length of life of each tungsten electrode before it is discarded. With ground and polished tungsten electrodes, mechanised welding can produce identical, repeatable results. The shape of the tungsten electrode is also important in manual welding: with a correctly shaped tip, the arc can be precisely positioned with none of the preferential arcing experienced when using poorly shaped, manually ground tips.

The eye-catching beams have been constructed using steel plate strips and cuttings supplied by SSAB. Normek Oy is the subcontractor responsible for the steel structures. SSAB supplied Normek with the steel

The Central Library Oodi is being built in a prime location in the city centre of Helsinki, Finland, situated between the Central Railway Station and Helsinki Music Centre. The library’s frame features steel beams that stretch into the sky and are around 100m long.

New tungsten electrode grinder Ensuring tungsten electrodes are sharpened correctly can help improve weld quality. Tungsten electrode grinders are a convenient, accurate and safer way of grinding tungsten electrodes. Huntingdon Fusion Techniques (HFT) has reinitiated the manufacturing of the TEG-2 tungsten electrode grinder, which it retired from its product range a number of years ago, under the new name TEG-1000. standard, with other sizes catered for on request. The diamond wheel grinds the tungsten electrodes longitudinally, preventing arc flicker or wander caused by circumferential lines or ridges found

HFT’s Georgia Gascoyne commented, “Since we stopped manufacturing the TEG-2 tungsten electrode grinder, we’ve been inundated with requests to bring it back into our product range.” TIG welding requires tungsten elec- trodes to have perfectly ground and polished tips. The TEG-1000 grinder gives repeatable tungsten electrode points, enabling consistent repeatable arc performance and welding results. Sizes 1 to 3.2mm can be ground as
