Should I enter the purchased filler weight?

Enter only filler retained in the finished welds. Purchased filler includes losses and unused inventory, which do not contribute to the weldment’s finished weight.

Can I use the assembly mass from CAD?

Yes, if the model includes the relevant materials and current component quantities. Check whether welds, hardware and finish are already included before adding their weights separately.

Does finish weight include wet paint?

Use the coating mass retained in the finished condition you intend to handle. Solvents that evaporate before handling do not remain in the cured coating weight.

Does being below the limit approve the lift?

No. The comparison checks entered weight only. The handling plan must also address equipment ratings, attachment points, balance, load geometry and any items moved with the weldment.

Welding & Fabrication calculator

Weldment Weight Calculator

Estimate finished weldment weight from its retained components. Enter net base weight, deposited filler, installed hardware, cured finish and your handling weight limit.

What this calculator does

Add the retained components of a finished weldment and compare the weight with your handling limit.

Formula used

Hardware and finish = installed hardware + retained finish
Added weight = deposited filler + hardware and finish
Total weight = net base material + added weight
Handling load (%) = total weight ÷ handling limit × 100
Weight headroom = handling limit − total weight

Inputs explained

Net Base Material: Finished plate, tube and structural weight after fabrication removals.
Deposited Filler: Filler remaining in the finished welds.
Installed Hardware: Total installed bolts, nuts, inserts and other hardware.
Retained Finish: Cured coating or retained galvanizing added to the assembly.
Handling Weight Limit: Entered allowable weight for your handling plan.

How to use the result

Best suited to finished weldment Handling, shipment weight planning.
Weight alone does not check lifting geometry, balance or equipment suitability. Packaging, fluids and temporary fixtures require separate inclusion when handled together.

Current U.S. benchmarks

The producer price index for steel mill products stands at 381.162 (BLS, Aug 2026), up 23.4% from a year earlier. Quotes priced off last quarter's material cost miss this move.
Industrial electricity averages 9.77 cents per kWh across the U.S. (EIA, Jul 2026), up 4.7% from a year earlier. Energy-intensive steps carry this directly into unit cost.
U.S. iron and steel import customs value ran $2.2B in Aug 2026 (Census International Trade). The U.S. ran a trade deficit of $0.6B in the category that month. This dollar total mixes price, quantity, product mix, origin, and timing; it does not measure physical import volume or prove a tariff or reshoring effect.
The U.S. has 53,790 fabricated metal products establishments employing about 1,441,471 workers (Census County Business Patterns, 2023).
