comment Can we weld two dissimilar metals without using LASER welding?
You just need to heat the two metals to above their melting points without allowing anything chemical to happen to them. Normally means heating them quickly without a flame - see friction welding

Interesting. I don't have the lab setup to immediately try this but it is worth considering.
