Reliable Aluminum Welding That Lasts

At 704 Diesel & Welding Services, we provide aluminum welding for customers who need strong, clean repairs and dependable fabrication work. Aluminum is lightweight, corrosion-resistant, and common in trailers, truck bodies, tanks, ramps, toolboxes, marine parts, and custom equipment. It is also a metal that takes the right process, the right setup, and real experience to weld correctly. That is where we come in.

We handle aluminum welding both in our shop and through our mobile service when the job and conditions allow. Based in Marshville, NC, we serve customers within about a 50-mile radius, including much of the Charlotte area and nearby parts of North and South Carolina. If you have cracked aluminum, broken welds, damaged components, or need a custom aluminum part built or modified, we are ready to help.

What aluminum welding involves

Aluminum welding is different from welding steel. The metal transfers heat fast, has an oxide layer that must be handled properly, and can distort if it is not welded with care. A good aluminum weld depends on proper cleaning, fit-up, filler selection, heat control, and the right welding method for the material thickness and application.

When we take on an aluminum welding job, we focus on more than just joining metal together. We look at how the part is used, where the stress points are, whether there is cracking from vibration or impact, and what repair or fabrication method will give you the best long-term result. Our goal is to provide a repair or weldment that performs well in the real world, not just one that looks good for the moment.

Common aluminum welding services we provide

• Repair of cracked or broken aluminum components
• Re-welding failed joints and damaged seams
• Aluminum trailer and ramp repairs
• Truck body, toolbox, and equipment repairs
• Custom aluminum fabrication and modifications
• Support bracket, frame, and mount repairs
• Patch work on damaged aluminum sections when appropriate
• Reinforcement of high-stress areas

Many customers call us when they have a part that has split, a bracket that has broken loose, or an aluminum structure that can no longer be used safely. In other cases, customers need a custom change made to existing equipment. We can inspect the problem, talk through your options, and recommend the most practical solution.

Types of aluminum items we often work on

Aluminum is used in many industries because it offers a good balance of strength and weight. We commonly work on:

• Utility trailers and landscaping trailers
• Loading ramps and liftgate components
• Aluminum truck beds and service bodies
• Toolboxes and storage compartments
• Equipment housings and guards
• Tanks, platforms, steps, and handrails
• Custom brackets, mounts, and structural pieces
• Light industrial and agricultural aluminum parts

If you are not sure whether your item can be repaired, it is worth reaching out. In many cases, a damaged aluminum part can be restored, reinforced, or modified instead of being fully replaced. That can save time and money, especially when replacement parts are expensive or hard to find.

Our approach to repair and fabrication

We start by looking at the condition of the aluminum, the location of the damage, and the purpose of the part. Some repairs are straightforward. Others require additional prep, crack removal, edge cleaning, beveling, or reinforcement. We take the time to prepare the material correctly because prep work has a major effect on weld quality.

For fabrication and modification work, we pay close attention to measurements, fit, function, and service conditions. If a part needs to carry weight, resist vibration, or match up with existing components, we build with those needs in mind. We do practical work for real use, whether the job is for a contractor, equipment owner, fleet operator, farmer, or homeowner.

We also understand that not every aluminum repair is worth doing. If a part is too thin, too contaminated, badly fatigued, or unsafe to restore, we will tell you honestly. We believe in giving customers clear recommendations so they can make the best decision for their equipment and budget.

Why experience matters with aluminum

Aluminum can be unforgiving. Poor welds can crack early, contaminate easily, or fail under load. That is why aluminum welding should be done by someone who understands material behavior, heat input, joint design, and the demands the finished part will face. At 704 Diesel & Welding Services, we bring hands-on experience to each job and treat every repair with care.

Our customers count on us because we are straightforward, responsive, and focused on quality work. We know that many aluminum repairs are not just cosmetic. They affect safety, function, uptime, and the ability to keep working. We take that seriously.

Mobile and in-shop aluminum welding

We offer both mobile welding service and in-shop welding depending on the type of aluminum repair or fabrication needed. Mobile service is a good fit when equipment cannot be moved easily or when on-site repair is the most efficient option. Shop service is often best for jobs that require more extensive setup, detailed fabrication, or controlled working conditions.

If you contact us about mobile aluminum welding, we can let you know whether on-site service is the right fit for the repair. Some aluminum work needs cleaner conditions, better access, or more stable positioning to get the best result. We will always recommend the option that gives you the strongest and most dependable outcome.

Who we serve

We work with a wide range of customers across the Marshville and greater Charlotte region. That includes owner-operators, contractors, small fleets, farmers, equipment owners, businesses, and property owners who need skilled welding work without the runaround. Since opening in 2022, our team has built a reputation for dependable service, honest communication, and practical solutions.

As a company run by Matt Harris, we take pride in doing the job right and treating customers with respect. When you call us, you are working with a local business that understands how important your equipment, trailer, or metal component is to your day-to-day work.

When to call for aluminum welding

You should consider professional aluminum welding if you notice visible cracks, separated joints, broken mounts, bent sections, fatigue around stress points, or repeated failure in the same area. Fast repair can often prevent more damage and reduce downtime. Waiting too long may turn a repairable issue into a larger replacement job.

If you need a custom aluminum part, a modification to existing equipment, or a repair on a trailer, truck body, ramp, or fabricated component, we are here to help. We can review the job, explain the options, and provide a straightforward plan.
