A 100 mm thick API 2W Gr. 60 steel plate was produced from a continuously cast stab on the basis of the fundamental study on the effect of chemical composition on toughness of HAZ. The application of TMCP could reduce the chemical composition and consequently resulted in good weldability and good toughness of welded joints. The HAZ toughness of the welded joint was evaluated by the three point bend CTOD test using K-groove submerged arc welded joints made with heat inputs of 0.8, 3.0 and 4.5 kJ/mm. The surface notched, wide plate tensile test was also performed using the welded joint made with a heat input of 4.5 kJ/mm. The applicability of the developed steel plate and its welded joints to offshore structures was studied using the flaw assessment procedures adopted by WES2805 and BSI PD6493.
