"Weld Sizing Design Criteria and Overwelding in Naval Surface Combatants"
in this .pdf. I read some interesting data and a whole lot of validation from the results of testing regarding some of the aspects with Weld sizing criteria besides the shocking to some but, realistic comparisons of costs related to fillet welds just from a change of 1/16" size difference... In short, a very good read IMHO... Check it out here:
