Self-shielded flux-cored weld consumables are increasingly used in the fabrication of offshore structures. The higher deposition rate obtained by flux-cored welding techniques is a major economic incentive in structural fabrications. However, lack of corrosion fatigue data on weldments made with flux-cored wire has been a major acceptance of this welding technique in marine structure fabrication. This paper reports the results from laboratory corrosion fatigue tests on weldments made of two types of flux-cored wires and the AWS E7016 electrode. S-N plots for each consumable were developed in a synthetic seawater environment to compare their corrosion fatigue behavior. In addition, the fatigue crack propagation behavior of weldments made from these electrodes were studied under free corroding and cathodically protected conditions. The implication of the data relative to the AWS "X" curve and their relevance to structural design and fabrication are discussed. Mechanical properties of weldments made from these consumables are presented.
