  • Uticaj reparature na nivo i raspodelu zaostalih napona u sučeonom zavarenom spoju mikrolegiranog čelika
    Vuherer, Tomaž ; Rojko, Danilo ; Gliha, Vladimir
    High residual stresses arise during welding. These stresses can attain yield strength of the material. They are caused by thermal cycles always present in joints made by fusion of materials. When a ... weld needs to be repaired, it is very rigid because repair welds are usually short and only a part of the thickness should be replaced. Residual stresses in the repaired welds are higher than those in normal welds. Residual stresses were experimentally determined on the surface of the multi-pass butt-welds before and after reparation. Longitudinal residual stresses are the highest in the weld metal. They approach the yield strength of the material. Transversal residual stresses are lower than the longitudinal ones. The residual stresses are higher after reparation than before reparation.
