Abstract

679,094. Uniting by fusion. TUBE TURNS, Inc. April 2, 1951, No. 7628/51. Addition to 622,550. Class 83 (iv). In butt-welding tubes, a welding ring having radial spaced projections is placed between the tube ends so that the projections engage the ends which are welded to each other and to the ring between the projections as in the parent Specification and the projections which are lightly welded to the ring are struck to break them from the ring before completing the welding. In one embodiment the ring 1 is provided with a groove 7 in which are welded cylindrical pins 8 by weld spots 9. In a modification each pin 8 has a portion of reduced section where it contacts the ring to form a space for the weld spots. The pins may be of oval or rectangular section and the ring outer surface may not be grooved.
