The main aim of this work, is to show for the welding engineers and/or designers of welded structures, the many existing options in the design of fillet welded joints, when loaded transverse, inclined, or parallel to the axis of the weld bead. This is done through a discussion on the very fundamental aspects of this kind of joint, a series of equations (from standards or Code) that allow the throat dimensioning, and examples using actual base metals and consumables. It is also a purpose of this paper to caution those professionals, for each one of the standards (such as AISC and Eurocode 3), or Codes (such as AWS), or even authoritative organizations (such as IIW), have specific characteristics (or "philosophies"), some of them very distinct. Finally, but not less important, this paper closes analysing fillet welded joints under concepts of the theory of elasticity and local plasticity.
