FIELD: process engineering.
SUBSTANCE: invention relates to repair of metal assemblies. Damaged part is built up with metal powder on said part. Said damaged parts are subjected to laser building up with the help of metal powder. Then hot isostatic pressing step is performed. Maximum temperature is set during isostatic pressing not exceeding temperature recrystallisation of said metal.
EFFECT: higher quality of repair owing to elimination of porosity in building up.
