Welding Calculations

Welding Calculations
Design Rules for calculating the strength of butt and fillet welded joints subject to Direct, Bending and Torsional loadings. Plus guidance on calculating centroids and second moment of area.

Just touch the F and B labels with the mouse pointer, don't click them.
 

        • Basics   A basic introduction into stress / strain relationships & weld design.   • T Fillet Weld   Formula for calculating the stresses in a fillet weld.   • Lap Fillet Weld   Formula for calculating the stresses in lap fillet welds subject to shear.   Cantilever   Fillet welded cantilever subject to bending and shear   Lap Joint Subject To Torsion   Fillet welded lap subject to Torsion and shear   Rectangular Block Subject To Torsion   Rectangular and fillet welded and subject to Torsion   T Butt Weld Subject To Torsion   Full Penetration T Butt welded Cantilever subject to Torsion   Lap Joint Subject To Bending and Shear   This calculation method is one I came up with. Unfortunately I couldn't find a similar joint in any technical reference to verify it.   Back Ground Information   Useful revision and helpful for understanding some of the above calculations.   Calculating Volume Using Solids Of Revolution   I came across this method when I was trying to calculate the volume of a dished head on a pressure vessel and found it useful to know.   Bibliography   Sources of my information and some useful references.
