Enter the electrode diameter (in), the wire feed speed (in/min), and the electrode efficiency (%) into the Weld Deposition Rate Calculator. The calculator will evaluate the Weld Deposition Rate. 

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

  1. First, determine the electrode diameter (in).
    • The electrode diameter (in) is calculated to be : 2.
  2. Next, determine the wire feed speed (in/min).
    • The wire feed speed (in/min) is measured to be: 3.
  3. Next, determine the electrode efficiency (%).
    • The electrode efficiency (%) is found to be: 98.
  4. 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)
