“…Taban, Kaluc, and Kocaeli [2] have considered application of the super-martensitic stainless steels (SMSS) as efficiently and effectively selected materials for fabrication of onshore and offshore pipelines. They also emphasized that fatigue loading behavior of welded structures, made of the super-martensitic stainless steels, has not been thoroughly investigated.Chen et al [3] presented an experimental studyof welding effects on tensile characteristics of the T-welds of the high-strength low-alloyed steel. Values of mechanical characteristics in the elastic zone, obtained experimentally, are higher than the related values calculated according to Eurocode 3 standard: steel constructions design [4], implying that the standard prescribes determination of the discussed weld characteristics of the HSLA steel in a conservative way.Zhang et al [5] presented experimental investigation of the welding influence on strength of the high performance steels and concluded that welding significantly softened the heat affected zone in the HSLA steel with insignificant effect on the normal strength.Durmusogly, Turker, and Tosun [6] were investigating gas metal welding (GMA) of the HY-80 steels with application of different welding parameters.…”
