Abstract

There should be tempered bead welding technology to cope with unexpected damage during operation of a nuclear power plant. Welding work should be urgently performed considering the safety of radiation exposure to workers without stopping operation of nuclear power plant. In this study, the tempering effect was measured by measuring the residual stress of the welded part by the tempered bead welding on the low alloy steel specimen, which is the main material of the nuclear reactor, by hardness of the base, HAZ and weld metal zone, And to develop the optimal tempering bead welding technology applicable to actual field.
