Weld Joint - Butt Joint Calculation - Bending Load
The following equations will determine the normal stress applied to a butt welded joint under going bending loading.
Normal
Stress Weld Formula
Where
: µ = Constant - for
calculation in metric units u = 1000 - for
calculation in imperial units u = 12 = Bending
moment [Nm, lb ft] W = Section
modulus of throat area of the weld [mm3, in3] Reference
Weld Stress Formula
σ2
= Normal stress [MPa,psi]
Where:
σs
= Reference stress [MPa,psi]
σ2
= Normal stress [MPa,psi]
α2
= Coefficient of weld joint
