How do I calculate weld deposition rate?

Deposition rate is wire feed speed times wire cross-sectional area times material density times deposition efficiency. The Weld Deposition Rate calculator returns pounds per hour, so 0.045 inch solid wire at 350 inches per minute with about 95 percent efficiency deposits roughly 11 to 12 pounds per hour of arc-on time. Multiply by Arc-On Time and Operator Factor to get real shift output, since a 30 percent operator factor cuts that theoretical rate to 3 to 4 pounds per billed hour.

What is a realistic operator factor and how does it change my cost?

Operator factor, or arc-on time, is the fraction of paid time the arc is actually burning, and manual welding often runs just 15 to 30 percent while automated cells reach 50 percent or more. The Arc-On Time and Welder Productivity calculators apply it to deposition rate. A shop assuming 100 percent arc-on will underquote badly; at 25 percent operator factor a weld that theoretically takes 10 minutes of arc time consumes 40 minutes of Fabrication Labor Cost.

How do I calculate weld heat input and why does it matter?

Heat input is voltage times amperage times 60, divided by travel speed in inches per minute, times arc efficiency, giving kilojoules per inch. The Weld Heat Input calculator runs that, so 28 V, 250 A at 12 IPM with 0.8 efficiency is about 28 kJ/in. Codes and WPS often cap heat input to control HAZ properties and distortion, and Weld Travel Speed is your main lever, since faster travel lowers heat input but can starve the joint.

How do I price weld cost per inch or per part?

Combine filler, gas, and labor per unit length. Welding Cost Per Inch pulls Weld Metal Required, Filler Wire Cost, and Shielding Gas Cost together with an arc-on labor rate, then Welding Cost Per Part multiplies by total weld length and adds Tack Weld Time and Weld Fixture Cost Per Part. Rework and inspection are easy to forget, so fold Weld Rework Cost and Weld Inspection Cost in on code or cosmetic work where reject rates move the true cost.

How do I choose between plasma, laser, and waterjet for a cut?

Cost per part depends on thickness, edge quality, and speed. The Laser Cutting Cost, Plasma Cutting Cost, and Waterjet Cutting Cost calculators price each by pierce count, cut length, feed rate, and machine rate. Laser wins on thin sheet speed and edge quality, plasma is cheapest on thicker mild steel, and waterjet handles thick, heat-sensitive, or exotic material with no HAZ. Run all three against Cut Length Cost to see which lands your part cheapest.

How do I calculate press brake tonnage and bend allowance?

Tonnage scales with material thickness, tensile strength, and bend length, and inversely with die opening. The Press Brake Tonnage calculator sizes the brake, so air bending 1/4 inch mild steel over an 8x die needs roughly 8 to 9 tons per foot. Sheet Metal Bend Allowance and Bend Deduction then correct your flat pattern for the neutral axis stretch, so a 90 degree bend in 0.125 inch steel adds bend allowance that must come out of the flat blank length.

Live market signals for this industry

The producer price index for steel mill products stands at 361.439 (BLS, Jun 2026), up 16.9% from a year earlier. Quotes priced off last quarter's material cost miss this move.
Industrial electricity averages 8.71 cents per kWh across the U.S. (EIA, May 2026), up 5.1% from a year earlier. Energy-intensive steps carry this directly into unit cost.
U.S. iron and steel imports ran $2.2B in Jun 2026 (Census International Trade). The U.S. ran a trade deficit of $0.4B in the category that month. Import volumes are the pressure gauge behind tariff and reshoring decisions.
The U.S. has 53,790 fabricated metal products establishments employing about 1,441,471 workers (Census County Business Patterns, 2023).
