Briefly Valtteri Bottas is contesting the GP3 Championship Tipped to be Finland’s next Formula 1 star, Valtteri Bottas could be seen in action in motor racing’s premier series as early as next season. He is rapidly building his career in the Williams organisation, which selected him as their official test driver in January 2010. In addition to his role at Williams, this season Bottas will also contest the GP3 Series for the ART team. He moved up to GP3 from the Formula 3 Euro Series, which he contested in the past two seasons. The GP3 Series has been described as GP2’s little brother, and GP2 is regarded as the last stage on the way to Formula 1. GP3 Series races are contested in conjunction with European Formula 1 race weekends, keeping Bottas in constant touch with the Grand Prix circus. ”This has helped to raise my profile and I get to spend time with the Williams team. It’s also important that the Series is contested with Pirelli tyres. Pirellis will be introduced to Formula 1 next season and so I’ll get some valuable experience,” Bottas says. Success in the GP3 Series will naturally help Bottas to become a Williams driver. His chances are also boosted by the fact that Rubens Barrichello, the team’s Brazilian driver, is already contesting his 19th season in motor racing’s top series and at some stage will make room for new and younger talent. Bottas does, however, need more experience and is taking things at a steady pace: ”I’ll contest one season in GP3, the next in GP2, and then I hope I can race in Formula 1,” he says.

Light mechanisation delivers efficiency – and better ergonomics Increasing productivity is the target in all areas of industry and other activities involving production. This self-evident mantra is repeated in all possible situations. The emphasis on efficiency is understandable, of course, because efficiency is accompanied by a lot of benefits: competitiveness, growth and prosperity. However, it often also involves unfortunate after-effects: job losses, a frenzied pace of work, decreased autonomy for employees. The demand for increased productivity in welding has been met by the development of more efficient and versatile welding equipment and the introduction of welding software for different applications. These improvements to equipment and software are increasing the quality and productivity of welding, but by far the best way of raising welding efficiency is through automation and mechanisation. Of these, mechanisation - and light mechanisation in particular - can be used in a very wide range of applications. Mechanisation means moving the welding torch mechanically. The welder sets the necessary welding parameters or selects them from the memory channel stored in the welding equipment. When the welding carriage is started it begins to follow the groove and produce a consistent quality weld. The welder’s task is to monitor the progress of the carriage and the quality of the weld. Light mechanisation is an easy and cost-effective way of improving welding efficiency, and it also has a favourable impact on ergonomics and safety. Exposure to arc radiation and welding fumes is reduced and working positions are improved because the machine does the physically heavy work while the welder can concentrate on monitoring the process. As a result light mechanisation of welding can, at least in certain cases, meet the requirement for increased efficiency without unfortunate side-effects for employees. In fact, there are benefits for the welders, as light mechanisation can make their work more enjoyable and safer. Success depends on many factors Equipment for light mechanisation typically consists of compact and lightweight wheeled tractors and rail carriages. This equipment can deliver a huge increase in welding speed: when manual welding achieves speeds averaging 20 - 40 cm per minute in the long run, light mechanisation makes it possible to reach speeds many times higher – speeds in excess of 100 cm per minute can be realised in horizontal fillet welds, for example. Welding mechanisation will only result in a clear increase in the efficiency of the production process if welding is the bottleneck that is causing production delays. The basis for successful mechanisation – and automation – is always the ability to understand the production of the workshop as a whole. After all, mechanisation will only result in a genuine increase in productivity if it enables the product lead-through time → © Pixmac Kemppi ProNews 2011 9
