The tube end portion complements or corresponds to the contour of the surface of a tube to which it is joined so that when the tubes are contacted with one another only the projections make contact thereby leaving a gap of uniform width between the pipes. After tacking the pipes together with projection welds, the gap around each joint is filled with brazing solder. | |
