<p>A method for assembling a direct injection fuel rail (10) of an internal combustion engine includes the steps of: designing a fuel distribution tube (12) having a first radius, mating a fuel rail component (14) having a second radius that is different from the first radius with the fuel distribution tube, forming at least one projection point (20) where the fuel rail component contacts the fuel distribution tube, consuming the at least one projection point during a resistance welding process, and forming a temporary bond between the fuel rail component and the fuel distribution tube. By intentionally mismatching the radii of fuel rail components, projection points are created that can be consumed during a resistance welding process. As the projection points are consumed, a temporary bond is formed between the fuel distribution tube and the fuel rail component, and a braze joint gap is optimized, which enables formation of a high quality braze joint.</p> |
