Wire brush and chipping hammer is all you need. You don't want to be grinding away all the metal you just laid down (unless you are doing a groove/bevel/fillet weld, in which case grind that shit flush).

Tips for long welds as well OP, say you are welding two 4 foot sections of plate steel together. Tack every 10 inches or so, then weld with the pattern in pic related. Your metal will expand when heated, you need to weld with this in mind or you might find the job deforms when cooled. I made this mistake a few times when starting out, its a bitch to have to grind all your welds open and go again.
