Minimum wall thickness for maximum quality

THE eccentricity and the resulting wall thickness of a product are important parameters for an excellent quality and last but not least for material saving. Sikora offers a new wall thickness control, which continuously assures a specified minimum wall thickness (minimum value) during the entire production process (see picture 1). The newly developed control from Sikora optimises the production under

consideration of the wall thickness and eccentricity measurement information. As a result, an over wall thickness is avoided. In the past, control concepts usually based on average values of the wall thickness, and did not take into account a product eccentricity. This results either in a shortfall of the wall thickness tolerance and thus to the production of scrap or in an increased demand

for material in order to guarantee the required minimum wall thickness. (see picture 2).

Flux cored wires HAVING started flux cored wire production in 2009, Gedik Welding has been widening its product range via R&D restructuring that includes butt and seamless flux cored wire production technologies. The advantages of flux

cored wire are high deposition rate, smoothness of seam, easiest functionality in every position and less distortion and stress as compared to shielded metal arc welding. Ever-changing and improving industrial applications create the demand

for flux cored wires of Gedik Welding especially for certain specific material groups. Gedik Welding – Turkey Website: www.gedikwelding.com
