It is unusual to get crystallization in mild steel. It requires carbon, and 1018 steel just doesn't have enough. The welding wire has a bit more, but I've never had problems welding outdoors in all weathers. Of course it doesn't get much below freezing here.
If you want to be sure, use a heat gun to preheat your metal, and to slow cooling of the welds.
If you want to be very sure, weld some sample pieces (coupons, in weldspeak) and try to break them. Maybe a good practice in any event, til you get used to the machine.
