I've read that canned salmon typically does not contain any preservatives.



On the other hand processed meat (such as ham) contains them.



Why are preservatives needed in some cases but not others?

    I am not sure I understand your question. Are you compared canned fish to some kind of canned meat, or are you comparing two totally different preservation techniques, like canning and curing, and asking why they are not done in the same way?

Canned salmon is pasteurized. Pasteurization uses heat to render a product safe. Hams are cured with salt and nitrites in some cases. Salt and drying greatly reduce water activity to render a product safe. Two different processes, both create a safe product.
