Can you weld a cracked truck frame?

Sometimes. We can repair many frame cracks with proper preparation and reinforcement. The repair follows the truck maker's recommendations, as federal rules require. Cracks through the flange, or a rail that's bent, may need a new rail instead. The tech will tell you which case you have before any work starts.

Do you do mobile welding at job sites?

Yes. Job sites, fleet yards, farms and truck stops are all fine. The area has to be safe to work in, and the weather has to let the metal stay dry. Tell us about the site when you call.

Can you fix trailer crossmembers without pulling the floor?

Often, yes. We can remove and replace many crossmembers from underneath. If the floor itself has rot where it meets the crossmember, the floor may need work too. We'll show you what we see.

Torch work means using an oxy-fuel torch to heat or cut steel. On trucks, we mostly use it to free seized nuts and bolts, especially rusted U-bolts and hanger bolts. We also use it to remove damaged sections before we weld in new steel.

Do you protect the truck's electronics when welding?

Yes. Before welding, the tech disconnects or isolates the batteries as needed. They keep the ground clamp close to the weld and protect nearby wiring and modules from heat and spatter.

Mobile Welding & Truck Frame Repair

Mobile welding means the welder comes to the truck. Neuman Truck Service does welding, torch work and frame and body repair on tractors, straight trucks and trailers wherever they sit. That could be a cracked landing gear brace in a drop yard, or a broken step bracket on a truck that has to roll tonight.

A good weld on a truck takes more than laying a bead. Frame rails are heat-treated steel, and the manufacturer has rules about where you can weld, drill or add a bracket. Trailer crossmembers, dump bodies and flatbed decks each need their own approach. The tech checks why something cracked before choosing a fix. A weld that ignores the cause just cracks again a few inches over.

Welding and Fabrication We Do On-Site

Frame brackets and crossmembers: Cracked spring hanger brackets, cab mount brackets, crossmember gussets and rusted-out crossmembers. We repair or replace them to the truck maker's guidance.
Frame rail cracks: We assess each crack first. We can repair some with reinforcement, per the manufacturer's recommendations. Others mean the rail needs replacing. You'll get a straight answer either way.
Trailer frames and crossmembers: Broken or rotted crossmembers, cracked main beams, rear impact guard damage and broken landing gear braces on vans, reefers and flatbeds.
Landing gear mounts: Landing gear legs and cross braces that tore loose or cracked when a loaded trailer came down too hard.
Body and deck repair: Dump body cracks, tailgate hinges, flatbed stake pockets, rub rails, headache racks and deck plates.
Steps, tanks and boxes: Broken step brackets, fuel tank straps and brackets, battery box mounts, toolbox mounts and mud flap hangers.
Torch work: We cut seized nuts and bolts free, heat rusted U-bolts and hanger bolts loose, and remove damaged sections before new steel goes in.
Custom brackets: We build simple brackets and mounts for lights, wet kit components and accessories from steel plate and angle.

How Mobile Welding Works

Call (651) 491-4136 and describe what broke and where. If you can, send a photo of the crack or the damaged part. The photo helps us tell whether it's a quick weld, a part replacement or a job that needs more planning.

On arrival, the tech cleans the area to bare metal and traces the crack to its end. Then they check the parts around it for the cause, such as a loose bolt, a bad bushing or a missing gusset. Before welding, the tech protects electrical components near the work. Welding current and modern truck electronics don't mix well. Next you get the estimate. The tech does the repair and inspects it before the truck goes back to work.

What We Can and Can't Do Roadside

We can do most bracket, crossmember, body and trailer welding right where the truck sits. Weather is the main limit. Welding needs dry, clean metal. In a downpour or blowing snow, we may wait, work under cover in your building, or make a safe temporary repair first.

Some frame damage is bigger than a weld. A rail that's bent, kinked or twisted from a collision needs straightening equipment. A rail with a long crack through the flange may need replacing. Federal rules in 49 CFR 393.201 say welded frame repairs must follow the vehicle manufacturer's recommendations. The rule also bans holes in the top or bottom flanges unless the manufacturer allows them. We follow that rule, and we'll tell you if your truck needs more than mobile work can give it.

Rust, Brine and Broken Steel in the Upper Midwest

Steel doesn't last long under salt. In Wisconsin, county highway departments plow and treat all state, US and Interstate highways for WisDOT, and they spray liquid brine too. Minnesota roads get the same treatment. Trucks that run up to Superior, US-53 through Spooner, or I-35 down to the Twin Cities collect that brine all winter. It works into seams and under brackets. By spring, you'll find crossmembers rusted through at the welds and bracket bolts that need a torch to come out.

Cold steel is also less forgiving. Brackets that were already cracked tend to break on frozen, rutted roads. A trailer dropped on frozen ground can bend a landing gear brace. Spring is a good time to clean and inspect the frame and the trailer underside, before the cracks get longer.

How Much Does Mobile Welding Cost?

Every welding job is different, so the price depends on the work. Welding a cracked bracket is quick. Removing and replacing rotted trailer crossmembers takes material and hours. Access matters too: a crack behind a fuel tank means removing the tank first. Travel and evening or weekend calls also affect the price.

You'll know the expected cost before the welder strikes an arc, because every job starts with an estimate. The work carries a 12-month warranty.

Welding That Goes With Other Repairs

Welding often pairs with other work on the same visit. We usually find cracked spring hangers during suspension repair. Broken landing gear, rotted crossmembers and damaged rear guards are regular trailer repair items. Work on dump bodies and wet kit mounts overlaps with hydraulic repair. A cracked frame or a loose body mount is an inspection item, so schedule the welding before your annual DOT inspection.

Called in with a tire emergency and got Ryan on the phone — genuinely great experience. He was insightful, patient, and gave excellent customer service, even though we ended up not using them for the repair. You can tell they run a friendly, helpful shop. Would definitely call them again next time we're in a bind.
