CONTROL LINK WELDING METHOD

摘要

PURPOSE: A control link welding method is provided to enhance the control link welding intensity by removing flush generated after a bonding process by the projection welding using the laser welding. CONSTITUTION: The welding method comprises the steps of:performing projection welding to weld a first and a second ring parts(110) and a road part(120) integrally; removing a notch part(344) to remove flush(150) formed in the projection welding step by melting the flush(150) using laser light and solidifying along the circumferences of the first and the second ring parts.; Thereby, the control link disperse the internal stress concentrated to the notch part so that the destroying intensity is improved. And the corrosion resistance is improved by preventing the infiltration of the corrosive materials such as salt through the notch part.
