    it is always better to have one piece, so bending is better. You have to check if the bending radius is possible for the material and geometry of your tube. In a welded part, you will always have the possibility of stress concentration, degraded material properties due to temperature and other practical problems. On the books and reports on the source there is plenty of data on joints (welded, riveted, fastened).
