gas-torch bronze welding processes are another.

But isn't that more akin to brazing?

The distinction is subtle and pretty minimal, that's for sure.

Brazing requires a generalised heating and a filler that flows by
capillary action. Take the same base materials and filler rod, but use a
smaller, hotter arc or O-A torch and you have bronze welding. The
heating is localised and the filler rod is worked in a pool, not just
flowing under its own volition.
