Abstract

This paper deal with redistribution of chemical elements around cladding surface of composite tube. Motivation is that change of chemical composition cause change in microstructure and mainly changes in mechanical properties. Local changes of mechanical properties can cause inaccuracy or wrong results obtained from FEM modeling of bending process of cladding tube. In short paper present redistribution of chemical elements caused by heat input during production of tube. Redistribution caused by heat input from weld attachment of connector which is used during production of membrane waterwall is discussed. Microstructure evaluation of base material and cladding layer is compared with measurement of hardness. Measurement of microhardness in specific areas of cladding tube was done. Microhardness is compared with measurement of chemical composition via EDX in scanning electron microscope.
