How much is a mobile welder per hour in Kansas City?

Roughly $100–$150/hr for the KC metro. KC Ironcore is $125/hr after the service call, which includes the first hour.

What's a service-call fee and why do I pay it before any work?

It covers the trip to you plus your first hour on-site. It's standard in mobile welding (trip fees run $150–$300 nationally, usually including the first 30–60 minutes). At KC Ironcore it's $225. Most small repairs finish inside that first hour.

Is mobile welding more expensive than taking it to a shop?

A bit more per hour, yes — because I bring the truck, trailer, and welder to you. But you skip hauling your trailer or equipment across town and losing it for days, which usually makes mobile the cheaper option overall on equipment and trailer work.

Why does aluminum cost more than steel?

The filler rod costs more, it takes shielding gas, the prep is fussier, and it takes more skill and time to get a sound weld. Across the trade aluminum runs 30–50% over mild steel; I price it at about 35%.

Can you give me a flat price instead of an hourly quote?

For defined-scope work, yes — send photos and I'll quote a flat number, usually same day. Structural, frame, and big fabrication jobs are quoted after I see them in person, because rust and access decide too much to guess.

How Much Does Mobile Welding Cost in Kansas City? (2026)

What mobile welding costs in the Kansas City metro in 2026: service-call fees, hourly rates, what moves the price, and real number ranges by job type — from a KC mobile welder.

How much does mobile welding cost in Kansas City?

Short answer for the KC metro: expect a service-call fee in the $150–$300 range that includes the first hour on-site, then roughly $100–$150 an hour after that, plus materials. At KC Ironcore that's $225 for the service call (travel + first hour) and $125/hr after. Most small repairs are done inside that first hour, so a lot of jobs land right around the service-call number.

That's the honest range. Below is what's behind it and what makes a job cost more or less — because "how much does mobile welding cost" doesn't have one answer any more than "how much does a car repair cost" does.

Why there's a service-call fee at all

A mobile welder isn't a shop. The truck, the trailer, the engine-driven welder, the gas, the insurance, the drive time across town — all of that is overhead before a single weld happens. The service-call fee covers the trip and your first hour on-site so a 20-minute weld doesn't lose the welder money. It's the standard model in this trade nationally — trip fees run $150–$300 and almost always include the first 30–60 minutes of work — and it's exactly how I price it.

It also means you know what you're walking into. A welder who shows up with no minimum and an open hourly clock is a welder who has every reason to take their time.

What the hourly rate looks like

After the first hour, mobile welding in this region runs about $100–$150/hr. The national "typical" is $100–$125; a pure Kansas-City read lands around $90–$125; certified, specialty, or emergency work pushes toward $135–$150. My rate — $125/hr — sits right in that band.

It's higher than a shop's hourly because I bring everything to you. The shop makes you haul your trailer or your equipment to them and lose it for a few days. Mobile costs a bit more per hour and saves you all of that.

What moves the price up

Aluminum and stainless — about 35% more than mild steel. Aluminum especially: the filler costs more, it takes shielding gas, the prep is fussier, and it takes more skill and time to do right.
After-hours, weekends, emergencies — 1.5× the rate, with a higher minimum (I set it at $300). When a fleet trailer cracks at 9 PM, that's what it costs to have someone actually answer.
Distance — the metro's covered in the service call; past about 30 miles from base I add mileage ($1.50/mi) or quote the trip flat.
Access and position — welding overhead, in a pit, lying under a trailer, or on a roof takes longer than welding at bench height.
Rust and surprises — if I get into a repair and the rust runs three feet past what was visible, the job's bigger than the quote. I'll stop and tell you before I keep going — no surprise invoices — but it's why structural and frame work is always quoted in person.
Materials — steel prices swing a lot ($44 to $125-plus per stick depending on the week). Materials are extra unless I quote them in.

Real numbers by job type

Starting points for the KC metro. These are ranges, not promises — the exact number comes from photos or a look:

Gate / fence repair (hinge, sag, cracked post): $175–$400
Trailer coupler / hitch / tongue repair: $200–$500
Trailer frame rail / crossmember repair: $400–$900 (quoted in person)
Utility trailer floor / deck repair: $300–$1,200 (quoted)
Railing / handrail repair (one section): $250–$800
Exhaust / muffler weld (one cut, one weld): $80–$200
Heavy / farm equipment repair (bucket, attachment, blade): $300–$1,500 (quoted)
Structural steel repair (beam, column, lintel): $500–$2,500+ (quoted — site visit)
Handrail fabricated & installed: starting at $85–$120 per linear foot installed, ~$700 minimum
Custom gate (simple): starting at $550; ornamental quoted
Truck rack / headache rack: $300–$1,200 (quoted)
Aluminum repair: $150 minimum, then time + 35% (quoted)

The national "average welding project" across all types runs roughly $120–$490, averaging around $300 — which is to say most jobs are a few hundred bucks, and the ones that aren't are the ones you'd expect (structural, big fab, multi-crack frame rebuilds).

How to get an exact price

Send photos. Seriously — a close-up of the break, a wide shot, rough dimensions, and where it is, and I can give you a flat quote for defined-scope work, usually same day. It's how this trade works and it's how you avoid me either eating a misjudged price or padding it to be safe. Open-ended or structural jobs get the service call ($225) and a quote on-site. Full breakdown on the pricing page.

What about the cheap guy?

There's always a guy with a welder in a truck bed who'll do it for less and take cash. Sometimes that's fine. But that guy usually isn't insured, can't send a COI, won't be reachable in six months if the weld cracks, and isn't going to be the one a property manager or a fleet keeps on a vendor list. If it's a fire pit in your backyard, price-shop away. If it's a trailer frame, a handrail an inspector's looking at, or anything that carries weight or people — pay for someone who'll stand behind it.
