Welded beam splice - partial pen weld? - Structural ...

Jul 24, 2012 · The reference that partial penetration welds of jumbo sections or thick material results in bending of the weld, is related to the size of the partial penetration weld specified. It is obvious if an E = 1/4 weld is the strength required for a 3" plate, a tensile force will result in bending at the weld root.
