## Welding Energy Formula

The following equation is used to calculate the Welding Energy.

**Ew = WP * T**

Variables:

- Where Ew is the Welding Energy (Joules)
- WP is the welding power usage (watts)
- T is the welding time (seconds)

## How to Calculate Welding Energy?

The following two example problems outline the steps and information needed in order to calculate the Welding Energy.

**Example Problem #1:**

- First, determine the welding power usage (watts). In this example, the welding power usage (watts) is measured to be 4.
- Next, determine the welding time (seconds). For this problem, the welding time (seconds) is calculated to be 3.
- Finally, calculate the Welding Energy using the formula above:

Ew = WP * T

Inserting the values from above and solving the equation with the imputed values gives:

Ew = 4 *3 = 12 (Joules)

**Example Problem #2: **

Using the same process as example problem 1, we first define the needed variables outlined by the formula. In this case, the values are provide as:

welding power usage (watts) = 9

welding time (seconds) = 5

Entering these values into the formula or calculator above gives us:

Ew = 9 * 5 = 45 (Joules)
