That would probably fall under not good, both in the aesthetic department and the not ideal for the integrity of the steel department. Are you certain it is not a bit of sloppy brazing, or a paint mishap? Can you post a photo of the wobbly area?
While you can certainly overheat a tube when brazing or welding, and that can affect the tubing to a degree, depending on what kind it is, I don't think the heat would be enough to deform the surface in the manner you describe. I could be wrong.
