Welding and Masonry Classes

No this isn’t about wood, but the two other main building materials, metal and stone. I am trying to find good DIY classes for welding and masonry in San Diego and all I can find are apprentice programs and community college certificates. Does anyone know of a place that would teach either of those subjects at a level like SDFWA teaches about wood?

I don’t know if it is still ongoing Palomar College used to have a metal set of classes with welding etc. Similar to the classes they have for wood. Not sure if that’s still ongoing but you could check it out.
