Mobile welding
Mobile welding in San Diego — we come to you.
When something breaks, you can't always haul it to a shop. Nautilus Industrial Marine brings certified welders and a fully equipped mobile rig to your job site anywhere in San Diego County — from the waterfront in Barrio Logan to job sites in Otay Mesa. Whether it's a cracked trailer frame at 6 a.m. or structural steel that has to be fixed before the crew shows up, we weld it on-site, the first time, to code.
Backed by the same NAVSEA-certified team that repairs U.S. Navy vessels, our mobile welding meets a standard most local shops can't match — now available for commercial and industrial jobs across the county.

Why San Diego businesses call Nautilus
We're not a general handyman with a welder in the truck. Our welders are certified in FCAW, GMAW (MIG) and GTAW (TIG) and work to marine and federal standards every day. That means your weld is done right, documented, and built to hold — whether it's a boat hull or a warehouse mezzanine.
