Application possibilities of low-temperature repairs by welding for creep-resistance material GX12CrMoVNb9-1
Original language description
Paper is focused on the area of the energy devices working under the higher temperatures and pressures. It deals with repair of new and operational-loaded components of steam and gas turbines (valve and turbine chamber, transmitters, vane carriers, flap-lockable valve bodies and so on). Generally, there occur different types of defects at production and operating of these parts. Many defects are caused by casting (shrinkage cavities, pores, cracks) and fatigue defects. Eventually, there can occur also production defects. Moreover, most of the defects in the mentioned parts generally take effect not until during the subsequent technological operations. However, in such phase of production, only welding technology can be used to repair the given part. That's why as a goal of this paper there was to find such repair welding procedures which ensure the serviceability of mentioned devices in the standard mode indeed at application of the lower tempering temperatures in comparison to the commonly requirements for material GX12CrMoVNb9-1. Lower tempering temperatures have a strong influence on elimination the deformation as well as on the surface oxidation of the machined components.
