Welding & Metallurgy Calculators
Determine professional welding setups, preheating conditions, steel grades equivalence lookups, hardness scales, and joint geometry.
MIG Welding (WFS ↔ Amp)
Calculate MIG wire feed speed (WFS) and matching amperage. Includes gas recommendations and presets for steel, stainless, and aluminum.
MIG Machine settings
Ensure standard travel angle of 10° - 15° push for gas-shielded wires (provides best shielding cover) or drag for flux-cored wire processes. Keep contact tip to work distance (stick-out) around 3/8" (10mm).
