I have never tried it or seen any posts regarding that here but as it IS steel, I would think it is possible. BUT, if you are not proficient at forge welding other types of steel, you will probably have yourself a time, trying to forge SS as your first project. From what I understand about SS, it has a very narrow forging temperature window, I would guess that forge welding it would be an even more narrow time slot.
