Szukana fraza: [Abstract = "In practice, in the design stage of revitalization, renovation or reinforcement, there is often a need to determine the strength of steel as well as its weldability. The strength of steel can be determined in two ways\: directly through destructive testing or indirectly \- by the Brinell hardness test. In the case of weldability, this turns out to be much more difficult, because there are three groups of factors which determine this property, i.e.\: local weldability, operative weldability, and overall weldability."]
