How to Start a Mobile Welding Business

How do you start a mobile welding business step by step?

Get certified, form an LLC, buy an engine-driven welder and rig out a truck, carry liability insurance, set your rates, then land your first paying job through farms, contractors, and trailer owners nearby.

Most mobile welders start the same way. They learn the trade at work or at a community college, buy a used engine-driven machine, and take small repair jobs on nights and weekends until the phone rings on its own. The steps below take you from zero to a first paying job in roughly 60 to 90 days.

• Get your skills certified. Take the AWS Certified Welder test in stick (SMAW) at minimum. Structural work runs on the AWS D1.1 code, so test to it.
• Form an LLC, get an EIN, and open a business bank account. This keeps job money separate and protects your personal assets.
• Buy an engine-driven welder. A used Miller Bobcat or Lincoln Ranger in good shape welds the same steel a new one does.
• Rig out a truck or trailer: machine, 100 feet of lead, grinders, a torch or plasma cutter, clamps, a vise, and fire extinguishers.
• Get insured before the first job: general liability of at least $1 million plus commercial auto on the rig.
• Set your rates. Pick an hourly rate, a trip fee, and a one hour minimum, and quote them without apology.
• Tell every farm, ranch, contractor, and trailer owner you know that you weld on site. Leave cards at feed stores and steel yards.
• Do the first jobs fast and clean, photograph your work, invoice on the spot, and ask for a Google review before you leave.

How much does it cost to start a mobile welding business?

Most solo welders spend $5,000 to $12,000 to start lean with a used engine-driven machine on a truck they already own. A dedicated new rig with a flatbed runs $23,000 to $50,000.

The welder itself is only part of the bill. The truck setup, hand tools, and insurance add up fast. Here is what a realistic 2026 budget looks like for a solo operator.

A lean start means a used machine in the bed of a truck you already own. That rig welds the same gate a $50,000 setup welds. Upgrade with profit, not debt.

What licenses, certifications, and insurance does a mobile welder need?

There is no federal welding license. Most mobile welders carry AWS certifications, a local business license, an LLC, general liability insurance of at least $1 million, and commercial auto coverage on the rig.

Welding has no state license the way plumbing or electrical does. What matters is who accepts your welds. Building inspectors, insurance companies, and commercial customers want code work, and code work means certified welders. Requirements vary by state and city, so call your local building department before taking structural jobs. Some cities require a licensed contractor for anything attached to a building, and a few big cities, like Los Angeles, keep their own certified welder list.

• AWS Certified Welder: the standard card. Test in stick (SMAW) and MIG (GMAW) first, on the AWS D1.1 structural steel code.
• API 1104 and ASME Section IX: pipeline and pressure pipe certs. Hard tests, and they raise your hourly rate the most.
• Business license and LLC: most cities and counties require a simple business license, usually $50 to $200 a year.
• General liability insurance: $1 million per occurrence minimum. Welding counts as hot work, so expect $1,500 to $4,000 a year.
• Commercial auto and inland marine coverage: these protect the truck and the machine bolted to it. Personal auto policies deny rig claims.
• Hot work rules: many industrial sites require a hot work permit, a fire watch, and an OSHA 10 card before you pass the gate.

How much should a mobile welder charge?

Most mobile welders charge $85 to $150 per hour plus a trip fee, with a one or two hour minimum. Emergency and after-hours calls run 1.5 to 2 times the normal rate.

Mobile welding is priced like a service call, not a shop job. You bill for the operator, the machine, and the trip together. Most solo rigs in 2026 land between $85 and $150 per hour, with rural repair work at the low end and code or pipe work above it.

Protect yourself with a minimum. A one or two hour minimum plus a trip fee keeps a 20 minute gate hinge from eating half a day. Quote materials separately and mark them up 20 to 30 percent.

How do you get your first mobile welding customers?

Start with people who break steel every week: farms, ranches, trailer owners, landscapers, construction crews, and equipment yards. A Google Business Profile, a lettered truck, and fast callbacks win most early jobs.

Your first customers are people whose equipment breaks in the field, where a shop cannot help them. Go where broken steel piles up, and make yourself the easiest welder to reach.

• Walk into feed stores, tractor dealers, and farm co-ops with cards. Many equipment dealers have no field service truck and will gladly hand out your number.
• Ask the counter crew at your steel supplier to refer you. Steel yards get asked for a welder every single day.
• Visit trailer dealers, equipment rental yards, and tow lots. Offer to handle their repair overflow at a fleet rate.
• Call landscapers, fencing crews, and small general contractors. Every one of them owns trailers, gates, and racks that crack.
• Set up a free Google Business Profile as a service-area business so you show up when someone searches for a mobile welder near them, then ask every customer for a review.
• Post before and after repair photos in local Facebook farm, ranch, and buy-sell groups. Broken trailer posts show up there weekly.
• Answer the phone nights and weekends for the first year. A breakdown call handled at 9 pm builds a reputation no ad can buy.

What equipment and software do you need for mobile welding?

You need an engine-driven welder, at least 100 feet of lead, grinders, an oxy-fuel or plasma cutter, clamps, and safety gear, plus simple software for invoicing, scheduling, and mileage tracking.

Buy the machine and safety gear first, then add the rest as jobs demand it. Everything below fits on one truck or a small trailer.

• Engine-driven welder: Miller Bobcat 260, Miller Trailblazer 325, or Lincoln Ranger 260MPX. It welds anywhere with no power hookup and doubles as a jobsite generator.
• Leads: at least 100 feet of welding cable so the truck stays parked while you reach the work.
• A suitcase wire feeder for MIG and flux-core work on thicker field repairs.
• Two angle grinders (one set up to grind, one to cut), a portable band saw, and an oxy-fuel torch set. Add a plasma cutter like the Hypertherm Powermax 45 XP when budget allows.
• Clamps, magnets, a 4 foot level, squares, and a bench vise mounted to the rig.
• Safety gear: auto-darkening helmet, flame-resistant jacket, leather gloves, safety glasses, two fire extinguishers, and welding blankets for fire watch.
• Software: a scheduling and invoicing app on your phone, simple accounting software, a card reader so customers can pay on site, and a mileage tracker for taxes.

Is a mobile welding business worth it, and what can you earn?

Yes, for a skilled welder who hustles. Many solo mobile welders gross $80,000 to $150,000 a year at 60 to 75 percent margins, since labor is the product and overhead stays low.

A realistic first year looks like this: a few part-time months while the phone starts ringing, then $40,000 to $70,000 in revenue as repeat farm and fleet work stacks up. Established solo rigs commonly gross $80,000 to $150,000, and pipeline or heavy equipment specialists beat that.

Margins are the draw. Fuel, shielding gas, wire, rod, and abrasives usually eat 15 to 25 percent of revenue, and the rest pays you. The work is seasonal: fence and trailer jobs peak spring through fall, harvest brings breakdown calls, and winters slow down in cold states except for snowplow repair and emergencies.

The welders who fail usually fail at business, not welding. Answer the phone, invoice the same day, and keep showing up, and the rig pays for itself inside the first year.
