Butt Weld Under Axial and Transverse Loading Formula

\(\large{ \sigma_{butt} = \frac{T}{l\;d}   }\)

\(\large{ \tau_{butt} = \frac{V}{l\;d}   }\)

\(\large{ \sigma_{avg} = \frac{\sigma_{butt} }{ 2 }   }\)

\(\large{ \tau_{max} = \sqrt{ \sigma_{avg}^2 + \tau_{butt}^2 }   }\)

\(\large{ \sigma =  \sigma_{avg} \;+\; \tau_{max}   }\)

Where:

\(\large{ \sigma_{avg} }\)  (Greek symbol sigma) = average stress of weld

\(\large{ l }\) = length of weld

\(\large{ \tau_{max} }\)  (Greek symbol tau) = maximum shear stress

\(\large{ \sigma_{butt} }\)  (Greek symbol sigma) = normal stress of weld

\(\large{ V }\) = shear force

\(\large{ \tau_{butt} }\)  (Greek symbol tau) = shear stress of weld

\(\large{ \sigma }\)  (Greek symbol sigma) = principle stress

\(\large{ T }\) = tensile force

\(\large{ d }\) = throat depth of weld
