Welders send estimates for custom fabrication, structural work, installs, and larger repairs where the customer wants a price before approving the job. Customers usually compare total price, material grade, finish, lead time, and whether the welder carries insurance and certifications. A clear written quote also protects you when steel prices change or the scope grows.
When to use estimates: Use estimates to provide project quotes and get client approval before starting work. Once approved, convert your estimate to an invoice with one click to collect payment.

Gates, railings, and brackets are easy to misunderstand. A sketch or dimensions with sign-off prevents arguments about size and design.
A36 steel, galvanized, stainless 304, and 6061 aluminum differ widely in cost and workability, so the quote must state what is included.
Certified or inspected welds take more time and documentation, and the cost should be agreed to before work starts.
Finishing is often outsourced or time-consuming. State what is included and who pays for third-party coating.
On-site install requires travel, lifting, anchoring, and sometimes permits, which may not be included in a shop price.
Metal prices move, so state how long the quote holds and what happens if material costs rise before the order is placed.
Sets expectations on when you buy material, start work, and expect payment, and shows lead time clearly.

|---|---|---|
| Mobile welding and repair (general) | per hour | $85-150 |
| Shop welding and fabrication | per hour | $65-110 |
| Certified structural or pipe welding | per hour | $90-175 |
| TIG welding (aluminum or stainless) | per hour | $80-140 |
| Trip or travel charge for mobile calls | flat fee or per mile | $50-125 flat, or $1-3 per mile |
| Custom gate or railing fabrication | per linear foot | $75-250 |
| Consumables (gas, wire, rod, discs) | percent of labor or flat fee | 5-15% or $15-60 |
| Minimum call-out charge | flat fee | $100-200 |
Typical US ranges. Rates vary by region, experience, and job size.
Estimate cutting, fit-up, welding, grinding, and finishing hours separately, then add materials, consumables, and outside services. Quoting from a total feeling instead of this breakdown is how fabrication jobs lose money.
Hidden damage, rust, or contaminated metal can double the work. For repairs, quote an estimated range or hourly with a cap, and state that you will contact the customer before exceeding it.
Give a choice such as painted mild steel versus galvanized or stainless. Customers can pick based on budget, and the choice documents what they approved.
For jobs needing drawings, engineering review, or multiple site visits, charge a design or estimate fee that is credited toward the work if the customer accepts.
Quick quotes for simple jobs are normally free. For complex projects that need site visits, drawings, or takeoffs, many welders charge a fee and credit it to the final bill if the customer hires them.
Fifteen to thirty days is common for fabrication because metal prices change. If the job relies on a large steel purchase, shorten it or add a clause that lets you adjust for material cost changes.
A flat quote means you absorb overruns unless the customer changes the scope. For hourly or repair work, give a range and agree to check in before going past it. Put any scope additions in writing.
For custom work, yes. Get a signed quote and a deposit before buying material so you are not stuck with cut-to-size steel if the customer cancels.
