    - Formula used to calculate shear strength of butt weld is given as P = τhl

    here,
    P = tensile strength of butt weld,
    τ = shear stress
    h = weld throat thickness
    l = total length of weld

    - Shear strength: It is defined as the strength of material against the type of structural failure where the component fails in shear.

    - Tensile strength: It is defined as the maximum amount of tensile stress a material takes before failure.
