Welding & Metallurgy Calculators
Determine professional welding setups, preheating conditions, steel grades equivalence lookups, hardness scales, and joint geometry.
Stick Electrode Sizing
Match stick electrode sizes (3/32", 1/8", 5/32") and classes (E7018, E6010, E6013) with optimal welding amperage ranges.
Electrode matching parameters
Electrode Class Nomenclature Tip
Take E7018 for example:
• E: Shielded Metal Arc Electrode.
• 70: Minimum tensile strength is 70,000 PSI (482 MPa).
• 1: Can be welded in all positions (flat, horizontal, vertical, overhead).
• 8: Low-hydrogen iron powder coating, runs on DCEP or AC.
Good match. Adequate penetration is expected.
Structural buildings, heavy bridges, pressure vessels, high crack resistance, low hydrogen.
