ABOUT WELDS WITH IN-PLANE ECCENTRIC LOADS

WHAT ARE WELDS WITH IN-PLANE ECCENTRIC LOADS?  

     * WELDS WITH IN-PLANE ECCENTRIC LOADS :

• Whenever possible, welds should be designed such that the line of force goes through the centroid of the weld group. When this condition is satisfied, the weld is usually the most economical and easiest to design. However, many times, it is not possible to satisfy such conditions
• The welded joint subjected to an eccentric load  'P' in the plane of welds.

     * Effect of in-plane Eccentric Load on Weld :

1. Parallel force (P):

• The parallel force through the C.G. of the weld group results in direct shear stress or primary shear stress.

       2. Twisting moment (T):

• The twisting moment about the C.G. of the weld group results in the torsional shear stress or secondary shear stress.
• In the stress analysis, the throat area of the fillet weld is considered. Hence any fillet weld is treated as a rectangle with throat thickness as its width.
