With carbon steel, finishing a weld is a fairly simple process. In the majority of cases, the steel needs preparing only to the extent where paint can be applied. A rough and well scratched surface will actually help the paint adhere better to the metal than if it were highly finished to a shine. In fact, where powder coating is going to be used to colour the metal, a coarse grained 2 step
