How to Start a Welding Business: Mobile Rigs and Contracts

Contents:

Skilled welders working hourly for a shop consistently earn far less than those running their own mobile welding rig, taking on-site jobs that shops can’t easily reach or don’t want the hassle of scheduling.

What You’ll Need

A welding certification (or strong provable skill), a mobile welding rig mounted on a truck, and general liability insurance before taking on any paying client work.

Numbered Steps

1. Get Certified or Document Your Skill

AWS certification, typically $200-$500 per process tested, isn’t always legally required but significantly increases client trust and opens doors to industrial and commercial contracts.

2. Build or Buy a Mobile Rig

A basic mobile welding setup, including a generator-powered welder mounted on a truck bed, costs $8,000-$25,000 depending on equipment quality and whether you build it yourself or buy pre-configured.

3. Get Properly Insured

General liability insurance for welding work, given fire and injury risk, typically runs $1,000-$3,000 annually, essential before any commercial or industrial contract work.

4. Price by Job Complexity, Not Just Time

Mobile welding services typically charge $75-$150 per hour, with structural or specialty work commanding higher rates than simple repair jobs.

5. Build Contractor and Industrial Relationships

Steady contract work from construction companies and industrial facilities provides far more predictable income than relying entirely on one-off residential repair calls.

Common Mistakes to Avoid

New mobile welders often underprice travel time and fuel costs into their hourly rate, eroding margin on jobs requiring significant driving distance. Others skip proper insurance, exposing themselves to serious liability given the fire and injury risks inherent to welding work.

A Cost Breakdown

Beyond the rig itself, budget $500-$1,500 for safety gear and initial consumables, plus ongoing fuel and equipment maintenance costs that should factor directly into your hourly pricing.

A Personal Example

A welder who spent three years working hourly at a fabrication shop launched his own mobile rig, building relationships with two local construction companies that now provide steady contract work worth more than double his previous shop salary.

FAQ

Do I need a specific business license for mobile welding?

A standard business license applies in most areas; some states or municipalities require additional contractor licensing for structural or commercial welding work specifically.

How much can an established mobile welder earn?

Established operators handling steady industrial contract work often net $70,000-$120,000 annually, depending on region and contract volume.

What welding processes are most in demand for mobile work?

MIG and stick welding cover the majority of field repair and fabrication jobs, while TIG certification opens higher-paying specialty work in food-grade stainless and aluminum applications.

Should I specialize in one industry or stay general?

Specializing in one industry, like agricultural equipment repair or structural steel, builds deeper referral networks faster than staying a generalist across unrelated industries from the start.

Next Steps

Build your rig and get insured before actively marketing, then focus on securing two or three steady contractor relationships that provide predictable work before relying entirely on one-off residential calls.
