Since the welded constructions produce easily stress corrosion cracking (SCC) or fatigue dis- ruption in corrosive medium or under ripple load, two methods inducing compressive stress on structural surfaces by anti-welding-heating treatment (AWHT) and explosion treatment (ET) are presented. The results show that they are good ways to resisting SCC on the welded 55400 steel or other components.
