IMPROVED LOCAL-CORROSION RESISTANCE OF WELDING OF Y.P. 350 N/MM2 CLASS STEELS FOR USE IN ICY SEAS

Local corrosion of the welding of offshore structures in icy seas is a serious problem, as the paint and cathodic protection system of the structures are damaged by the impact of ice. For this reason, the fabrication of offshore structures requires the following consideration: (1) Local corrosion resistance of welds. (2) Excellent low temperature toughness of base metal and welds. (3) Steel products, welding materials and processing methods which take into consideration of weldability ranging fro small heat input repair welding to large heat input repair welding to large heat input high efficiency welding. This paper discusses research which led to the development of better quality steel products, welding materials and processing methods which satisfy the above requirements.
