This work studies the combined effect of resistance spot welding (RSW) and post-welding sensitization on the degree of sensitization (DOS) of AISI 304 stainless steel (SS) by using EPR and DLEPR tests. The combined effect of RSW and post-welding sensitization at 750 °C gives rise to an overall DOS that: (i) is lower than that of the state without prior welding; (ii) that decreases initially with increasing sensitization time but then increases. This behaviour is due to the fact that the interdendritic corrosion (IDC) located in the weld metal decreases with increasing sensitization time.
► The combined effect of RSW and post-welding sensitization influences on the DOS. ► The DOS is lower than that of the state without prior welding. ► The DOS decreases initially with increasing sensitization time but then increases. ► Sensitivity of EPR is greater than that of DLEPR at shorter sensitization times.
