Enter the welding power usage (watts) and the welding time (seconds) into the calculator to determine the Welding Energy.

## 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)

To calculate the welding energy, multiply the welding power by the welding time.

## 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:

1. First, determine the welding power usage (watts). In this example, the welding power usage (watts) is measured to be 4.
2. Next, determine the welding time (seconds). For this problem, the welding time (seconds) is calculated to be 3.
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)
