No, it's upgrading the weapon into the better one.

Like 12.7cm -> 12.7cm Kai Ni (which is basically can't be crafted and only stock-in Ayanamai/Yuudachi Kai Ni) with 10 times modding. Also the same goes on 61 quad -> 61 quint and others.

But when you once did completely modding a type of weapon (Complete modding 12.7cm to 12.7cm Kai Ni) After you do crafting and got the new 12.7cm, it'll eventually in +3. (Only if receiving from craft, I assume)
