Some high yield reinforcing steel is not weldable. You have to do a metalurgical study or at very least, a carbon equivalency.

Yes, you can weld a high strength low alloy (HSLA) steel as stated above. Will you alter (e.g. weaken) it? Yes, locally you will alter mechanical properties because of the heat from welding.
However, this local alteration of mechanical properties can be compensated for in design by using a proper filler metal that is either as strong or even stronger in comparison to the base metal strength. Preheat requirements and interpass temperature will help to reduce problems related to welding high strength low alloy steels. The key is to minimize heat input to avoid softening the bulk properties of the base metal.
