Abstract
A manufacturing process of an offset-type fuel delivery rail assembly for an internal combustion engine. The offset-type assembly features offset distances between an axial centerline of an elongated conduit and those of tubular sockets for receiving fuel injectors. The process comprises the steps of clamping a conduit with a chucking tool, lowering a cutting blade onto the conduit to form arcuate edges corresponding to outside curvatures of tubular sockets, attaching the tubular sockets to the arcuate edges of the conduit by spot welding, and then brazing or welding around the arcuate edges to form an integral assembly. The cutting blade is formed into a solid circular configuration having an oblique plane. The cutting blade may be provided with a pair of longitudinal slots in order to form projections for concentrating electrical current during spot welding.
