Right, although it's also possible to use a carbon arc according to my books.

Right again. Brazing is basically a form of high-temperature solder, it works
well below the melting point of the steel, so there's less distortion. It's
also a lot stronger than lead/tin solder (although still not as strong as steel)
and hence very suitable for things like repairing fenders. Also works well for
joining dissimilar metals (like steel to cast iron).
