Easy-to-use tool helps to ensure solid, reliable joint. Tool similar to automobile-tailpipe expander corrects out-of-roundness in tubes before butt-welded and holds tubes in position during welding. Two tubes rounded and aligned with each other by expansion shoes. After use, shoes retracted so tool withdrawn, even through tube narrower than its mate.
