Strength of Butt Welded Joint Calculator

Calculate Strength of Butt Welded Joint







Formula

The formula to calculate the Tensile Stress in Weld (σt) is:

\[ \sigma_t = \frac{P}{b_{ns} \cdot L} \]

Definition

Tensile Stress in Weld is the average stress experienced by the Weld Beads when the joint plates are brought to tension. Tensile Force on Welded Plates is the stretching force acting on the plates that are welded. Beam Width for Nominal Shear is the shortest/least measurement of the beam. The Length of Weld is the linear distance of the welding segment joined by the welded joint.

Example Calculation

Let's assume the following values:

Using the formula:

\[ \sigma_t = \frac{16500}{0.015 \cdot 0.0195} \approx 56410256.4102564 \]

The Tensile Stress in Weld is approximately 56410256.4102564 Pa.
