Welding Cost Formula For Different Welding Processes
Return to MENU How to calculate Total Labor & Material Cost per Pound of Deposited Weld Metal Welding Cost Formula A/C + FD + L / RG = Total labor and material cost per pound of deposited weld metal A F C D L R G
Example :
= = = = = = =
Price per pound of electrode or wire Price per pound of flux Deposition efficiency (%) Pounds of flux used per pound of metal deposited Cost of labor and overhead Deposition rate in pounds per hour % Arc time (operating factor)
Manual Arc - 3/16 Postalloy 214 @200 amps ( $8.00/lb) / .70 + ($25.00/hr) / (3.75 x .35) = $30.66 GMAW - Postalloy 2898-SPL @ 200 amps ($5.00) / .98 + ($25.00/hr) / (8 x .60) = $11.95
