What is welding?

Welding is a process that unites multiple pieces of metal or thermoplastic materials by skillfully melting and fusing them together using energy sources ranging from gas flames and electric arcs to precise lasers and powerful electron beams.

This process plays an integral role in submarine manufacturing and offers numerous benefits:

Ensuring strength and structural integrity

It allows for the creation of strong and durable joints between metal components that can withstand challenging conditions, including high water pressure and dynamic forces.

Enabling weight efficiency

It eliminates the need for mechanical fasteners such as bolts and rivets by creating seamless connections that distribute loads more efficiently, which is critical for submarines to achieve desired buoyancy and maneuverability.

Creating watertight seals

It plays a crucial role in ensuring that the submarine's hull and compartments remain impervious to water ingress. It requires working with both thick and thin materials, careful technique, alignment, and a delicate touch.

Offering flexible designs

It allows for the creation of complex shapes and structures and enables the creation of customized and precisely fitting components.

Providing quality control

It can be closely monitored and controlled to ensure high-quality welds using non-destructive testing methods, such as ultrasonic testing and X-ray inspection, to detect defects ensuring that they meet the stringent quality standards required for submarine construction.

Saving money

It is a cost-effective building method that eliminates the need for additional fasteners, simplifies the assembly process, requires minimal maintenance over the life of the submarine, and reduces labor and material costs.

Build unbreakable bonds

Your work as a welder helps make submarining possible. The dependable structures you create help ensure the safety and integrity of our Naval submarine fleet. 

Imagine this scenario: A critical pressure test is being conducted on a newly designed submarine. As the submarine ventures down 3,000 feet below the surface, it faces intense pressure that could easily threaten the integrity of the vessel should water find its way in. Thanks to your solidly welded watertight hull, the submarine remains secure, passes the test, and is ready to take on real-life missions.

The components you create in your career will make safe and effective submarining possible and will help propel the future of U.S. Navy submarines.


The welders are who put it together. We make sure that that submarine is watertight so that when our people go out there our welds are going to keep them safe.”
