## Weld Deposition Rate Formula

The following formula is used to calculate the Weld Deposition Rate.

WDR = 13.1*D^2*FS*EE/100

- Where WDR is the Weld Deposition Rate (lbs/hr)
- D is the electrode diameter (in)
- FS is the wire feed speed (in/min)
- EE is the electrode efficiency (%)

To calculate the weld deposition rate, multiply the electrode diameter squared by the wire feed speed and the electrode efficiency, multiply this result by 13.1, then divide by 100.

## How to Calculate Weld Deposition Rate?

The following two example problems outline the steps and information needed to calculate the Weld Deposition Rate.

**Example Problem #1**

- First, determine the electrode diameter (in).
- The electrode diameter (in) is calculated to be : 2.

- Next, determine the wire feed speed (in/min).
- The wire feed speed (in/min) is measured to be: 3.

- Next, determine the electrode efficiency (%).
- The electrode efficiency (%) is found to be: 98.

- Finally, calculate the Weld Deposition Rate using the formula above:

WDR = 13.1*D^2*FS*EE

The values provided above are inserted into the equation below and computed.

WDR = 13.1*2^2*3*98/100 = 154.04 (lbs/hr)

**Example Problem #2**

The variables required for this problem are provided below:

electrode diameter (in) = 5

wire feed speed (in/min) = 6

electrode efficiency (%) = 7

Test your knowledge using the equation and check your answer with the calculator.

WDR = 13.1*D^2*FS*EE/100 =** **(lbs/hr)
