Large Part Welding
Napoleon Machine has the tools and expertise needed to handle most large part welding projects. However, our core focus is metal tube and heavy plate welding, from half-inch to 10 inches (0.25 m). Also, we can handle any part weighing up to 70,000 lbs.
Our success in large part welding has been made possible by expert tradesmen. When dealing with large weldments, an experienced team is essential. For example, large weldments can require a substantial amount of continuous weld, which will result in thermal expansion, and too much growth will cause the part to bend, bow, and warp. Rest assured, our team has hundreds of years of combined large part welding experience. Moreover, every welder holds multiple AWS certificates. If you have a job that calls for WPS/PQR, we have a full-time CWI.
We work hard to service our customers. That means delivering quality parts on time, every time. However, if we make a mistake, we’ll do what it takes to make it right. Please don’t take our word for it; read our customer reviews. Or, if you would like to chat with our team, email sales@napoleonmachine.com.

Quality built into every process.
Properly inspecting parts is an important aspect of our business. However, if you are catching errors during the inspection process, it is often too late. There are significant expenses associated with rework, and many times errors will lead to late deliveries. This is why we build quality into every process. For example, we have kickoff meetings for each job. Our welders, machinists, programmers, project managers, and painters meet and review technical data in close detail. This helps iron out potential issues on the front end. We have also invested in the BLUCO Floor Rail System, which is a precision modular welding tool.
Inspection Tools:
- Magnetic Particle
- FARO Laser Tracker
- Dye Penetrant
- Ultra-sonic

Here are two examples of our large part welding capabilities. On the right is a 40 by 20-foot steel skid built for the oil and gas industry. Our team put a lot of weld and heat on this product. Yet, they were able to keep the flatness under 1/8 of an inch over the product's entire length and width.

“I asked our Production Manager to inspect the table top you delivered 2 weeks ago, the results were some of the best we’ve seen. The paint looked good and they arrived well packaged. I wanted to pass along the feedback, which is particularly impressive since this is the first table top you’ve made for us.”
