Tubing roller use and care steel, copper and aluminum tubing.
Seamless tube, while generally more expensive, has several benefits over welded tube. Many of its benefits stem from the uniformity of its composition, as it has no welded seam. In general, the uniformity promotes increased corrosion resistance, higher tensile strengths, and a greater resistance to pressure when compared with welded tube.

Yes, the typical dom is in fact welded, its actually a friction pressure lap weld, there is no type of filler used, the tube is drawn over a spinning mandrel by two other spinning mandrels, the extreme pressure and friction from the spinning roller welds the pipe. True seamless is done by actually shearing a hole thru solid billet material.
If the rollers are lightly resting on the tube then it will clearly just pass through them without bending, but as the roller pressure is increased the tube will begin to deform, becoming concave on the side of the single roller as the two outer rollers try to push it around the inner roller.
