RESEARCH ON THE REHABILITATION OF PARTS
HARD SURFACING
The article presents a commonly used method for rehabilitation of parts
by welding load. The quality of rehabilitation is assessed by a set of
characteristics that give the reconditioned piece, the ability to meet the
necessary requirements, operating under normal conditions. Welding
instructions through material loading, are applied to the achievement of Francis
rotors type, on two components 1.4317 (GX4CrNi13-4)/SR EN 10213-2 cast
steel. These steels are ideal in terms of use conditions, where wear resistance
is really important, such as on hydraulic turbine components.
