It can't be a weld obviously since that can only

There are plenty of heterogeneous welding processes around. They're
somewhat obscure, but they're common enough when you need them. All you
need is a filler material that is easily dissolved in the parent
material - nickel rods for arc welding cast iron are one, some of the
gas-torch bronze welding processes are another.

But isn't that more akin to brazing?
