The surfacing technologies are used for constitution of protection layer against wear and is destined for obtaining coating with high
hardness. Among many weldings methods currently used to obtain the hard surface layer one of the most effective way of hardfacing is
using flux cored arc welding. This additional material gives more possibilities to make expected hard surface layer.
Chemical composition, property and economic factors obtained in flux cored wire are much richer in comparison to these obtained with
other additional materials. This is the reason why flux cored wires give possibilities of application this kind of material for improving
surface in different sectors of industry.
In the present paper the imperfection in the layers was used for hardfacing process in different situations to show the possible application
in the surface layer. The work presents studies of imperfection of the welds, contains the picture of microstructures, macrostructures and
shows the results of checking by visual and penetrant testing methods.
