Can you weld one type of metal to another type?

Question

Example (weld iron to steel)

Answer 1

Buddy, welding iron to steel is roughly equivalent to welding iron to iron- steel is usually iron with carbon in it. I'd try it, but test it first, and go slowly. It may have a tendancy to become brittle if rushed so fast a marked difference exists between alloys.

Good luck.  

Answer 2

sure! some use things like thermite to weld, it just makes iron fuse with 2 pieces of steel.

Answer 3

Sometimes, with varying degrees of success, depending on the alloys and methods involved.  

Answer 4

iron to steel somewhat aluminum to brass NO
