Abstract
A method and product for forming a joint between intersecting sections of tubing for the conduct of fluid flow. For forming the joints, there is included a section of primary tubing which is drilled or punched to form a radial aperture defining the location at which the joint is to be formed. To effect joinder with the primary tube, there is provided a secondary tube having an end that includes a pilot portion extending rearward from a recessed end plane and which merges with an integrally shaped saddle bead formed about the tube periphery. Inserting the pilot end of the secondary tube into the provided aperture of the primary tube enables the saddle bead to incur a contour overlay against the outside diameter of the primary tube for effecting lateral alignment therebetween while enabling joinder by welding, brazing or soldering. Also disclosed is the method of forming the secondary tube to produce a recessed end face/saddle bead combination by the use of upsetting swaging dies.
