Welding & Fabrication Services in Bedford Park & Melrose Park, Chicago, IL

Comprehensive Welding & Fabrication Services for Diesel Trucks and Fleets

Our welders are proficient in all major welding methods and select the right technique based on the material, thickness, and application. We don't use one method for everything.

MIG Welding - Best for heavy-duty structural applications - truck frames, trailer crossmembers, thick steel components. Fast, strong, and built to handle the stress of commercial hauling.

TIG Welding - Used for precision work on thinner or more delicate components - exhaust systems, stainless applications, aluminum, and situations where a clean, accurate weld matters as much as strength.

Stick Welding - Ideal for thick materials and field-grade repairs. Penetrates deep into heavy steel - reliable on the components that take the most abuse.

Custom Fabrication Services

• Custom exhaust systems & exhaust manifold fabrication

Custom Exhaust Systems for Heavy-Duty Trucks

A custom exhaust system isn't just about sound - it affects backpressure, engine efficiency, and emissions compliance. Fleet Master designs and fabricates custom exhaust configurations for heavy-duty diesel trucks, taking into account engine size, power output, and your specific operating requirements.

Whether you need a full custom exhaust build, a manifold repair, or a section replaced with properly fitted pipe, we fabricate it in-house rather than cobbling together off-the-shelf parts that don't quite fit.

Frequently Asked Questions

What types of welding do you do on trucks? We use MIG, TIG, and stick welding depending on the application. MIG for heavy structural work like frames and crossmembers, TIG for precision and exhaust work, and stick for thick steel components that need deep penetration. We'll use the right method for the job - not just the fastest one.

Can you weld a cracked truck frame? Yes. Frame cracks are one of the more common structural repairs we handle. Depending on the location and severity of the crack, we'll weld, reinforce, or fabricate a repair that restores structural integrity. We'll assess it first and tell you what's needed.

Do you fabricate custom parts? Yes. If a part is unavailable, hard to source, or needs to be built to a specific configuration, we fabricate it in-house. Brackets, mounts, exhaust components, fuel tanks, headache racks - if it can be built from steel, we can build it.

Do you do exhaust welding and fabrication? Yes. We repair cracked exhaust manifolds, weld exhaust pipes and flex sections, and fabricate full custom exhaust systems for heavy-duty diesel trucks. All work is done in-house.

Can you weld trailer components? Yes. Trailer structural work - crossmembers, frame rails, fifth wheel plates, kingpin repairs, and other structural components - is handled at our Bedford Park location.

Do you offer mobile welding? Certain welding repairs can be handled by our mobile units on-site within a 50-mile radius. Call 708-415-0251 and we'll let you know if your repair qualifies for mobile service or needs to come into the shop.

How long does fabrication work take? It depends entirely on the scope. A bracket repair or exhaust weld is often same-day. Custom fabrication builds or structural frame repairs take longer. Call ahead with the details and we'll give you a realistic timeframe.
