Our story
Meet Bay City Welding
Bay City Welding is a mobile welding service based in San Francisco, run out of a small shop by Mark. Whether you need a quick fix on the road or a job scheduled in advance, we bring the same care and craft to every project.
We've cut bed frame legs on a Sunday afternoon, fixed a motorcycle kickstand within the hour for a rider passing through from San Diego, and welded a car's a-arm the same day it broke down. When other shops don't pick up the phone, we do.
We show up on time, quote a fair price, and do the job right the first time. If you need a welder in San Francisco, call and talk to Mark directly.
- Owner-operated by Mark
- On-site or in-shop repairs

“Kickstand on my motorcycle broke in the middle of my trip from San Diego. I called Mark super last minute and he saw me within the hour! Super solid work, super affordable. Super funny and helpful.”
“Mark is a remarkable guy. I needed a quick weld done on the a-arm of my car to get me through my next paycheck and he was able to see me same day! Fair priced even for the inconvenience I put him through. Pay him a visit for all of your welding needs!”
