BlueCollarSteel density
Carbon steel is commonly estimated at about 490 lb/ft³ (0.283 lb/in³) for field weight calculations.
WELDERS / FABRICATORS
Welding / Fabrication
Weld math, plate/pipe weight, layout and fabrication references. Use the tabs below to switch between working calculators and quick field-reference material.
Field-reference aid. Use approved drawings, current codes/standards, manufacturer data and job-specific procedures for final decisions—especially for lifting, electrical, pressure, fire-protection and life-safety work.
Heat input
Common formula: kJ/in = (Volts × Amps × 60) ÷ (travel speed in/min × 1000). Apply process efficiency only when your procedure requires it.
Fillet weld size
Actual weld size and acceptance come from the WPS, drawing and applicable code—not a generic calculator.
Before welding
Confirm base metal, filler, preheat/interpass limits, polarity and WPS requirements.
