A mobile welding business is one of the lowest-barrier entries into self-employment in the trades. You need a truck, a welder, skills, and customers. The startup costs are manageable, the demand for on-site welding repair is steady, and the income potential beats most shop welding jobs once you’re established.
The realistic first-year picture: $60,000-$100,000 in gross revenue, $40,000-$65,000 in net income after expenses, growing to $100,000+ net by year 2-3 as your customer base builds. It’s not instant wealth, but it’s a solid small business with real earning potential.

Licensing Requirements
Licensing varies significantly by state and municipality:
States requiring a contractor’s license for welding: California, Arizona, Nevada, Oregon, and several others require a contractor’s license for welding work above a certain dollar threshold. Check your state’s contractor licensing board.
States with no specific welding license: Many states don’t require a specific welding license. A general business license and liability insurance are sufficient.
Municipal requirements: Some cities require business permits, home occupation permits (if operating from home), or fire department inspections. Check with your city’s business licensing department.
Specialty licensing: Structural welding on buildings may require AWS D1.1 certification. Pressure vessel work requires ASME qualifications. Pipeline work requires API 1104. These aren’t government licenses, but clients and inspectors require them.
Pricing Strategy
How to Calculate Your Shop Rate
Your hourly rate needs to cover all expenses plus profit. Here’s the calculation:
Annual overhead costs:
- Truck payment and maintenance: $8,000-$15,000
- Insurance: $3,000-$7,000
- Fuel: $4,000-$8,000
- Consumables: $3,000-$6,000
- Phone, marketing, software: $2,000-$4,000
- Equipment replacement/repair: $2,000-$4,000
- Taxes (self-employment 15.3% + income tax): 25-35% of net income
- Total overhead: $22,000-$44,000/year
Billable hours (realistic):
- 40-hour work week, but only 50-65% is billable (rest is driving, quoting, admin)
- Billable hours: 20-26 hours/week x 48 working weeks = 960-1,248 hours/year
Rate calculation:
- Target income: $70,000/year
- Plus overhead: $35,000
- Total needed: $105,000
- Divided by 1,100 billable hours: $95/hour minimum
That’s the floor. Your market rate should be higher to account for slow weeks, unbillable time, and profit margin.
Common Pricing Methods
Hourly rate: $75-$200/hour depending on location and work type. Simple and transparent. Best for repair work with unknown scope.
Per-job (flat rate): Quote a fixed price for defined work. Better for the customer (they know the cost upfront) and better for you if you’re fast. Requires experience estimating accurately.
Per-foot pricing: Common for repetitive work like handrails ($25-$60/linear foot installed), pipe fencing ($15-$30/linear foot), or structural steel ($8-$20/linear foot welded).
| Job Type | Typical Price Range |
|---|---|
| Farm equipment repair | $75-$150/hour + materials |
| Handrail fabrication/install | $30-$60/linear foot installed |
| Gate fabrication | $500-$2,000 per gate |
| Trailer repair | $100-$500 per repair |
| Custom brackets/mounts | $75-$300 each |
| Pipe fencing | $15-$30/linear foot |
| Structural repair | $100-$200/hour + materials |
Material Markup
Mark up materials 15-25% over your cost. This covers the time and gas spent picking up materials, stocking your truck, and the risk of unused inventory. Don’t be bashful about material markup. It’s standard practice in every trade.
Minimum Service Call
Set a minimum charge ($150-$300) for any job. It costs you time and fuel to drive to a location, set up, and drive back. A “quick 10-minute repair” still takes an hour of your time when you count travel and setup.
Finding Customers
First 90 Days
Your initial customers come from your existing network:
- Friends and family. They know you weld. Ask them to spread the word
- Previous employers. Offer mobile repair services they can subcontract
- Local businesses. Visit farms, construction companies, equipment rental shops, and fencing companies. Drop off a card and explain your services
- Online presence. Google Business Profile (free), Facebook business page, Craigslist service ads
Common Revenue Sources
Farm and ranch repair: Broken implements, gates, feeders, corral panels, trailer hitches. Farmers need on-site repair because they can’t bring equipment to a shop. Rural mobile welders stay busy during planting and harvest seasons.
Construction subcontracting: General contractors need miscellaneous welding: anchor bolt installation, structural connections, handrail fabrication, equipment repair. Establish yourself as a reliable sub.
Property management: Apartment complexes, commercial properties, and HOAs need handrails, gates, dumpster enclosures, and security bollards maintained and repaired.
Trailer repair: Horse trailers, utility trailers, flatbeds. Floor replacement, frame repair, hitch work. Trailer repair is steady year-round.
Custom fabrication: Gates, signs, furniture, artistic metalwork. These jobs tend to be higher-margin but less frequent.
First-Year Revenue Expectations
Conservative Estimate
- 20 billable hours/week x $100/hour = $2,000/week
- 48 working weeks/year = $96,000 gross
- Minus expenses ($35,000) = $61,000 net before income tax
Optimistic Estimate
- 25 billable hours/week x $125/hour = $3,125/week
- 48 working weeks = $150,000 gross
- Minus expenses ($45,000) = $105,000 net before income tax
Realistic First Year
Most new mobile welders land somewhere between $60,000 and $100,000 gross in year one. The first 3-6 months are slower as you build your customer base. Revenue ramps up as repeat customers and referrals kick in.
By year 2-3, established mobile welders with a solid reputation typically gross $120,000-$200,000 and net $70,000-$120,000 after expenses.
Common Mistakes to Avoid
Underpricing. New business owners undercharge because they’re afraid to lose the bid. Calculate your actual costs and charge accordingly. A shop rate below $85/hour probably doesn’t cover your true expenses when you account for unbillable time, vehicle costs, and self-employment taxes.
Not having insurance. One incident without insurance can end your business and personal finances. Get general liability on day one.
Chasing every job. Some jobs aren’t worth the drive. If a customer wants you to drive 45 minutes each way for a $150 repair, you’re losing money. Set a service area and stick to it.
No written estimates. Get the scope in writing and have the customer approve it before you start. This prevents disputes about what was agreed to and what the price should be.
Mixing personal and business finances. Open a separate business bank account. Use it for all business income and expenses. This makes tax time simpler and protects your LLC liability shield.
Ignoring marketing. Word of mouth is great, but it takes time to build. Invest in a Google Business Profile, a simple website, truck lettering, and business cards from day one. Make it easy for people to find you and contact you.
Building a Seasonal Strategy
Most mobile welding businesses have seasonal patterns. Understanding them helps you plan cash flow and marketing:
Spring (March-May): Farm repair picks up heavily as planting season starts. Broken equipment that sat all winter needs fixing now. Fence and gate work increases. Construction season begins. This is your marketing push period for farm and ranch clients.
Summer (June-August): Construction subcontracting peaks. Outdoor projects (fencing, handrails, structural repairs) are easier to schedule. Heat makes the work harder, but demand is strong. Plan your highest-revenue months here.
Fall (September-November): Harvest season brings another wave of farm equipment repair. Construction projects rush to finish before winter. Trailer repair increases as ranchers prepare for livestock hauling season.
Winter (December-February): Outdoor work slows significantly in northern states. Indoor shop work, trailer repair, and maintenance welding carry the revenue. This is the time for equipment maintenance on your own rig, continuing education, marketing planning, and building your quote pipeline for spring.
Cash flow strategy: Save 20-25% of high-season revenue to cover slow-season expenses. If your monthly overhead is $3,000, keep a $9,000-$12,000 buffer for the lean months. Some mobile welders diversify into indoor work (fabrication subcontracting, shop overflow work) during winter to maintain steady income.
The welders who build seasonal awareness into their business planning avoid the feast-or-famine cycle that sinks many first-year operations. Track your monthly revenue from the start so you can predict patterns and plan accordingly.
A mobile welding business is built on skills, reliability, and reputation. Do good work, show up on time, charge fairly, and treat customers well. The repeat business and referrals that follow are what build a sustainable income. The welders who succeed at this aren’t always the best welders in town. They’re the most reliable and easiest to do business with.
