Marine Metal Fabrication
Metal fabrication involves creating and welding metal parts and assemblies. There is far more to the UMX process than cutting, burning, welding, machining and grinding materials to blueprint specifications. Keep reading for a glimpse at the approach our professionals take to bring your underwater welding vision to life.

1. Project Design and Planning

Whether we’re developing custom blueprints or working from an existing plan, we meticulously note every detail of your project. We’ll factor in site and material considerations as well as functionality and design objectives. The lines of communication are open for customer feedback as we make any needed changes before finalizing plans.

2. Project Build and Testing

Once plans are finalized, the build process can begin. The materials used will vary by project and budget but range from stainless steel, aluminum and steel, brass, copper, galvanized metal and more. When creating everything from platform decking to custom barges and marine ladders, we use computer-aided design and computer-aided manufacturing (CAD/CAM) software and the industry’s best hand and power tools.

Each project is unique, but typically the build process involves the following:

– Welding

– 3D or laser cutting

– Pressing and forming metal

– Finishing metal

– And more

All of our projects go through a quality control process to ensure materials meet and exceed industry standards.

3. Project Installation and Inspection
With safety at the forefront, the UMX team begins the installation process. Whether the majority of the work happens offsite or onsite depends on the project. A combination of installation techniques will be employed, such as welding, riveting, joining and more. We go through a careful inspection process with durability and safety in mind.

Due to the nature and location of the project extreme efforts were used to eliminate any impact on the marine environment, which was critical to the successful completion of the project. Any delays in the process would have had significant impact on the project schedule and cost. The UMX team completed the installation without incident and to the client’s satisfaction.
