You're absolutely right Jim. Many times it's called braze welding. 
Unfortunately when you tell someone they will "weld" something they're not 
going to look any farther because they think of sparks, arcs and something 
they can't do. Fortunately you can braze even copper to copper with simple 
materials available at the local Home Depot.

And that's an excellent choice if it's available :)
