TIG, for sure. Look around in your area for a welding supply company and see if they offer classes. Maine Oxy in New England has some good classes.

This is truly an art, but not a black art. The key is knowing how when to stop before getting into serious trouble (melting the ends of your stock) and how to fix mistakes.

Then...
Practice.
