Electrode Count (approx.)36 rods
Estimated Electrode Cost$26.55
Estimated Welding Time1 hrs
How to Use This Calculator
  1. Enter the total weld metal weight in lbs required for the joint (use the Weld Metal Volume calculator to find this).
  2. Set the deposition efficiency (%) for your process: SMAW ~65%, MIG ~95%, TIG ~100%.
  3. Enter the number of passes and the wastage percentage (stub loss, spatter, slag).
  4. Read Electrode Weight Required (lbs) — this is the total electrode weight to order accounting for all losses.
  5. Note Number of Electrodes (approx.) and Estimated Electrode Cost for your welding budget.
  6. Compare with the Welding Cost Estimator to build a complete weld cost per joint.

What each input means

Weld Metal Weight
Total weight of weld metal to be deposited.
Deposition Efficiency
Percentage of electrode that becomes weld metal (SMAW ~60-65%, GMAW ~90-95%).
Number of Passes
Number of weld passes required to complete the joint.
Wastage
Expected material loss from stubs, spatter, and grinding (typically 10-20%).

How this is calculated

Worked example, using the default values

  1. Identify Input Parameters
    4 parameters
    Weld Metal Weight = 5, Deposition Efficiency = 65, Number of Passes = 1, Wastage = 15 = 4 input(s) provided
  2. Calculate Electrode Weight Required
    Electrode Weight Required
    8.85 = 8.85
  3. Calculate Electrode Count
    Electrode Count
    36 = 36
  4. Calculate Estimated Electrode Cost
    Estimated Electrode Cost
    26.55 = $26.55
