A reinforcement beam for an automotive component is continuously formed with a metal sheet that is roll formed to have at least one tubular portion that extends along a length of the reinforcement beam. A solid state forge weld is formed between an edge of the metal sheet and an intermediate portion of the metal sheet to close a seam that extends along the tubular portion of the reinforcement beam. Prior to forming the solid state forge weld, select portions of the metal sheet are heated to a desirable welding temperature with a high frequency current delivered by electrical contacts to opposing sides of the weld seam. The desired welding temperature may burn off a galvanized coating on the metal sheet at the select portions prior to forming the solid state forge weld that is generally void of zinc inclusions.

A method for forming a forged and welded split gear rim involves forging a full circular ring using a large ring rolling mill and cutting it into two semi-circular rings. Radial extrusion using hydraulic jacks and a square box prevents radius expansion after the full circle is cut, reducing the radius of the semi-circular rings to their pre-welding radius. A tie rod fixture then fixes the reduced-diameter, straightened semi-circular rings, allowing for heat treatment while maintaining the radius dimensions. Finally, removing the tie rod fixture and machining the components allows the two semi-circular rings to be welded into a full circular rim. This method eliminates the need for large plate rolling machines to bend steel plates into arc shapes and for extending the ends of the steel plate as clamps. Therefore, it reduces costs in terms of both equipment and materials used. This simplifies the production process, enabling manufacturers without large plate rolling machines or access to large quantities of high-strength steel plates to produce forged and welded split gear rims.
