Corten steels are widely used in ship building railway constructions and some structural applications due to high hardness, high strength to weight ratio and excellent toughness. Shielded metal arc weldingwere used for fabrication of joints using low hydrogen ferrite steel consumables.
The joints fabricated by SMAW process using LHF exhibited superior fatigue crack growth resistance.
Due to heterogeneity induced from welding, base metal (BM) and weld metal (WM) have different mechanical behaviors. For structural steels, the strength of the welded joints determines the strength of the whole structure. Welded joints are subjected to various forms of cyclic loading in practical applications and fatigue failure is common. Thus, welding is a major factor in the fatigue lifetime reduction of
components. Failure analysis of the weldments indicated that fatigue alone is to be considered for most of the failures. This present study assumes significance as fatigue crack growth studies have not been reported in this class of corten steel fabricated.
