Comparative Evaluation of Mesoscale Sensitivity to Crack Formation in Multi-pass Welds Using Wires IN52 and IN52MSS
Assessment of susceptibility of multipass welds, produced by using wires ERNiCrFe-7 (IN52) and ERNiCrFe-13(IN52MSS), to crack formation was carried out. The PVR test was used to determine susceptibility to cra...
