3-axis two-in-one For the first time, operators of multi- purpose lines can make use of a sector gauge head with integrated 3-axis diameter measurement function for measuring ranges of up to 100mm. With this technology Sikora reacts to customer demands for multi-function measurement systems for different product applications in one production line. The ‘two-in-one’ gauge head is based on a newly developed sandwich principle. For this application the Laser 2100 S/R is combined with the Laser 2100 T. According to requirements the sector or diameter measuring function can be chosen. The measuring principle of the Laser 2100 S/R is based on a combination of three laser diodes as light sources with a CCD-line sensor in one plane. The height of stretched sector cables, which can be solid or stranded, is defined from the position of the edges that define the object. Even if the product turns up to ±15˚ the height is accurately determined. The Laser 2100 S/R is appropriate for the measurement of sector conductors with a cross section of A max =750mm 2 (for 120°-sectors) and A max = 500mm 2 (for 90°-sectors). The outer diameter and ovality of round cables is also calculated with an optical measuring principle. With the three laser

New thermal spraying wire The obvious solution to steel corrosion is to galvanise but, in extreme conditions, a galvanised structure can have a short life and it is very difficult to re-galvanise at a later stage. Thermal spraying of pure aluminium or pure zinc is also recognised as a good way of preventing corrosion with aluminium having a longer life but the concern with aluminium is that it tends to passivate in mildly corrosive environments. A new alloy wire for thermal spraying has been developed to bridge the gap between zinc and aluminium. CJ Wiretech Ltd, in conjunction with the BAC Group, is offering an aluminium-zinc-indium wire for arc or flame spraying. This alloy has been used before as solid sacrificial anodes in marine environments but it is now freely available as a wire from the BAC Group. AlZnIn is basically an aluminium alloy where the added zinc and indium behave as ‘activators’ to prevent passivation. The material is therefore suitable for thermal spraying directly onto steel and will act as a sacrificial protector in all corrosive environments where salt is a concern. This means that any onshore or offshore steelwork can be protected for 25 years or more against the ravages of corrosion. An added advantage is that AlZnIn alloys have been used for many years for the sacrificial protection of steel rebars embedded in reinforced concrete. The alloy is sprayed onto the surface of the concrete and electrical connections are made between the sprayed layer and the rebars, thus giving a protection as if there was a direct contact between the two metals. The idea is not new but in the past it has been difficult to source wires for the process; they are now available from CJ Wiretech Ltd. CJ Wiretech Ltd – UK Email : chris@cjwiretech.org
