Metal properties and residual stresses are studied experimentally in repair welds of steel 15Kh1M1FL casing components with use of a surfacing layer by UONI 13/55 and UONI 13/45 grade electrodes, and the permissible temperature range is evaluated for use of this kind of weld based on metal stress-rupture strength data.
