Welded rod fitting damper manufacture

摘要

A method of manufacturing a suspension damper with a welded rod fitting includes attaching a piston rod to a piston assembly. The piston assembly with the attached piston rod is inserted into a tube so that the piston rod extends from the tube. Hydraulic fluid is added to the tube either before or after the piston assembly is inserted. A rod guide assembly is slidingly received over the piston rod and is secured to the tube. An end fitting is secured in a weld fixture. The tube, containing hydraulic fluid, the piston assembly, the secured rod guide and the extending piston rod is positioned so that the piston rod abuts the end fitting. An electrical current is passed through the end fitting and the piston rod. The piston rod is moved away from the end fitting forming a gap as the electrical current is passing through the end fitting and the piston rod so that an arc is established across the gap to weld the end fitting to the piston rod.
