Weld Joint - Butt Joint Calculation - Bending Load

Weld Design Menu

The following equations will determine the normal stress applied to a butt welded joint under going bending loading.

Weld Joint - Butt Joint Calculation

Normal Stress Weld Formula

Normal Stress Weld Formula

Where :

σ2 = Normal stress [MPa,psi]

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

Reference Weld Stress Formula

Where:
σs = Reference stress [MPa,psi]
σ2 = Normal stress [MPa,psi]
α2 = Coefficient of weld joint
