    Abstract: A method for manufacturing a gear, which may be utilized as a side gear in a vehicle differential, with the method including the steps of selecting a first billet of low carbon steel and producing an annular gear wheel therefrom, and selecting a second billet of low carbon steel and making an annular gear hub therefrom. The method further comprises the step of bonding the gear wheel to the gear hub. Both the producing and making steps may comprise the step of forging a gear wheel and gear hub, respectively, near net forming the hub and wheel, or net forming the hub and wheel. The step of joining may be accomplished by laser welding or alternatively, by applying adhesives to mating surfaces of the hub and wheel. Due to the use of separate billets of low carbon steel to produce or make the wheel and hub, the wheel and hub may be made of different materials.

    Abstract: A method for gas metal arc welding a first component formed of nitrided steel to a second component with reduced porosity in the weld is provided. A welding wire including a core surrounded by a tube is used to weld the components. The material of the core is formed of mild steel including 0.7 to 3.0 wt. % aluminum and 0.7 to 1.5 wt. % titanium. The material of the tube is formed entirely of low carbon steel. During the weld process, the nitrogen from the nitrided steel combines with the aluminum and titanium of the welding wire to form aluminum nitride and titanium nitride, instead of nitrogen bubbles which lead to high porosity. The method can be used to weld components used in automotive applications, for example to weld a ring gear and can of a flexplate, but alternatively could be used for another automotive or non-automotive applications.
