Sorry to dredge up an old thread, but I'm looking for this as well and was wondering if the OP ever figured out a solution
I took a course a couple of years ago, sounds exactly what your looking for, I had never welded before and wanted to learn and incorporate it in my furniture.
The class was one evening a week for three hours (I think). It was great fun.
I am sure this is what your looking for and it was not expensive. You may even get in a class that starts this September if you call soon. Good luck.
