Tool for Trimming the Heads of ElectricallyWelded Tubes When tubes are electrically welded in place, it is im-possible for the welder to leave the ends smooth anduniform in appearance. The eye has become so accus-tomed to the beaded ends in the firebox tube-sheet thatit is .regarded as the proper form, hence the tool whichis illustrated here.
