## Weld Section Modulus Formula

The following two example problems outline the steps and information needed to calculate the Weld Section Modulus.

WSM = s^2*L / 6

Variables:

- WSM is the Weld Section Modulus (mm^3)
- s is the plate thickness (mm)
- L is the length of weld (mm)

To calculate the weld section modulus, square the plate thickness, then multiply by the length of weld divide by 6.

## How to Calculate Weld Section Modulus?

The following steps outline how to calculate the Weld Section Modulus.

- First, determine the plate thickness (mm).
- Next, determine the length of weld (mm).
- Next, gather the formula from above = WSM = s^2*L / 6.
- Finally, calculate the Weld Section Modulus.
- After inserting the variables and calculating the result, check your answer with the calculator above.

**Example Problem : **

Use the following variables as an example problem to test your knowledge.

plate thickness (mm) = 3

length of weld (mm) = 10

WSM = s^2*L / 6** **= ?
