Butt End Weld Joint Calculation Formulas Inventor 2016

Butt end weld loaded with normal force Normal stress where:F n normal force [N, lb] A throat area of the weld [mm 2 , in 2 ] Reference stress where: 1 normal stress [MPa, psi] 1 factor of the weld joint [-] Butt end weld loaded with shear force Shear stress where:F t shear force [N, lb] A throat area of the weld [mm 2 , in 2 ] Reference stress where: shear stress [MPa, psi] 2 Calculating weld stress under bending load using Shigley Apr 11, 2007 · Take the moment divided section modulus as calculated from Blodgett to get the maximum stress in the weld due to bending. Square both of the preceeding values and take the square root of that. That will give you the maximum shearing stress in your weld group. Compare that to your allowable weld stress (based on your effective throat).

Calculation of fillet welds loaded in the plane

while for the x-component of stress that actuates in the investigated point of weld, DETERMINATION OF WELD LOADS AND THROAT as weld joints, the plotted stress is the average of the stress in each side of the discontinuity. To identify the stresses (and loads) in a part at a discontinuity (weld joint), the stresses must be calculated for one side of the discontinuity only by activating results for the area of interest only, as is shown by the comparison of figures 4 How to Determine the Shear Strength of a Fillet Weld Clause 2 of AWS D1.1 requires that the minimum tensile strength of the filler metal be multiplied by 0.30 to obtain the allowable shear stress on the weld. The calculation is the exact same as when calculating the strength of a transverse fillet weld, except for the safety factor.


For a deep penetration weld, the depth of penetration should be a minimum of 2.4 mm. Then the size of the weld is minimum leg length plus 2.4 mm. The size of a fillet weld should not be less than 3 mm or more than the thickness of the thinner part joined. Minimum size requirement of fillet welds is given below in Table 1. Effective throat thickness should not be less than 3 mm and should not exceed 0.7 t and Weld Stress Analysis (FEA) SDC Verifier

The rotational stress is combined with the shear stress, then a resultant is determined using the square root of the sum of the squares. Weld Stress Calculation - Newcastle UniversitySlide 4 of 23
