A new procedure for sizing fillet welds for commercial ship structures is developed in this report. First the weld sizes required to develop the full strength of the type connections are developed including appropriate corrosion allowances. Service experience data is included by determining the joint efficiencies in the current American Bureau of Shipping ABS weld tables. ABS welds are resized and put in a form which is easier to use in a design office, easier to compare to other rule weld sizes, and should help guide further weld size reduction research although significant further reductions in commercial ship fillet weld sizes are not excessively conservative so the proposed reductions are relatively small. The new design criteria is applied to three sample ships showing order of magnitude weld cost savings of 9 to 15 percent. Keywords Joint efficiencies, Stress, Shear, and Electrodes.
