Welded Connection Under Static Loading.

In a butt weld, two parts are joined together by the weld that fills the V-grove between the parts. Consider a butt welded connection subject to a tensile load and/or a shear force as shown the figure. The resulting stresses acting in the weld are described by the equations below:

where
     L = length of weld
     H = throat depth of weld
     P = tensile force
     V = shear force
     σ_butt = normal stress in weld
     τ_butt = shear stress in weld
     σ_avg = average stress in weld
     τ_max = maximum shear stress
     σ₁ = principal stress
