Construction & Fabrication

Construction and Fabrication Connects our World. Hobart® filler metal connects structures.

From small construction jobs, to large bridges and skyscrapers, confab welding projects demand high-quality welds — which means you need filler metals you can count on: Hobart® filler metals.

Poor weld quality hurts your projects — and your company.

Welding is critical to structural projects, so don’t compromise: Hobart provides superior weldability for a wide range of applications. From light construction and home fabrication projects to large structures like the San Francisco-Oakland Bay Bridge, Hobart has the solution.

It’s the tie that binds STABILITY + TRUST

Every day, 250,000 vehicles pass over the San Francisco-Oakland Bay Bridge. To ensure safe journeys, engineers responsible for the integrity of the bridge’s structural steel depended on Hobart filler metals — see why.
