Axxair orbital global process FOR the past 15 years, Axxair has developed a global package proposal including orbital cutting, orbital bevelling and orbital welding machines. It is able to respond to the highest quality standards requested by industries such as aerospace, semiconductor, pharmaceutical but also lower rated standards such as in food and beverage where the price is an important issue. petrochemical using thicker pipes, Axxair has launched the SASL300, which offers modularity with the full version integrating arc voltage control, oscillation control, cold wire control and efficient high capacity cooling allowing the use on tube to tube sheet production applications.

coated parts,” commented team coordinator Ralf Wittkowski. “By using zinc-magnesium hot-dip coated starting material, we achieve better corrosion protection results with thinner zinc coatings. Water consumption is also reduced: by using two five-stage cascade rinses we have reduced the amount of water we need by 8,000 litres per hour.” The planning phase for the extensive modernisation of coil-coating line 3 began three years ago, and the project was finally implemented last fiscal year. During the three-week shutdown when the chemcoater was installed, maintenance and cleaning work to ensure defect-free operation of the line was carried out. The paint- and film-coated steel produced on coil-coating line 3 is supplied in the form of coil, slit strip and cut-to-length sheets for use in the construction, appliance, garage door and auto industries. ThyssenKrupp Steel Europe AG – Germany Website: www.thyssenkrupp-steel-europe.com This technical global approach would not be as efficient without a strong worldwide network of subsidiaries and partners that allows Axxair to be close to its customers in Asia and from its Korean Office, in Europe from its French headquarter, its German subsidiary and its Spanish office and in the USA through its future subsidiary in Texas. In a quickly changing environment, service has to be a top priority – service means technical innovation to provide equipment with higher productivity, offering technical advice for sorting out the most appropriate solutions, reacting quickly with a complete range of machines being available on stock and offering high level training all around the world in more than five different languages.

THE new chemcoater on coil-coating line 3 at the Siegerland location of ThyssenKrupp Steel Europe improves workflows on the coil-coating line, where paint and film coatings are applied to thin steel sheet, and actively contributes to protecting the environment. The chemcoater is a piece of equipment used in the steel industry to apply chemical substances to galvanised flat carbon steel. These substances are water-based media with additives that pre-treat the steel and increase the corrosion protection of subsequent paint and film coatings. The chemcoater carries out chemical pre-treatment processes required for the subsequent painting process. A total of three different chemicals can be applied to the sheet via rolls. The unit operates on the basis of a reuse process so that no wastewater is produced except in the subsequent rinsing operation. “This €6mn investment virtually eliminates the need for chromium-based corrosion- protection pre-treatments for organically Being able to respond with the widest range of orbital cutting machines from 5 to 1,100mm in diameter combined with unique prefabrication machines as well as open heads and closed heads, Axxair has the capacity to manage the whole tubing process. Therefore, it says it allows higher service proposal, better training capacities and less process interferences for higher return on investment. Its patented orbital bevelling system allows prepping of pipes in seconds – the carbide tipped J heads are the ideal solution to prepare pipes to be orbitally welded.

With its new orbital power source SASL160, it is able to offer affordable systems starting at less than €15,000. Such price categories allow quicker return on investment. The technical capacity was not compromised and the SASL160 offers all necessary functions such as auto programming, printing of parameters, 200 programs stored on a flash card, real parameter acquisition, and step mode welding for example. For industries such as chemical and
