  • STAMPING AND WELDING METHOD AND APPARATUS FOR FORMING A HOLLOW OR TUBULAR MEMBER WITH HIGH TOLERANCES
    Publication number: 20190262883
    Abstract: A method of forming a hollow metal member may include stamping a metal blank to form half shell pieces that are configured to be approximately a half of a hollow metal member and stamping a another metal blank to form a half shell piece that is configured to be approximately the other half of the hollow metal member. The half shell pieces may be aligned to place the edges of the first and second half shell pieces in abutting contact. The half shell pieces may be welded together along seams that are defined at the abutting edges of the first and second half shell pieces. The attached half shell pieces may then be compacted to form the hollow metal member with reduced residual deformation from stamping and welding the half shell pieces.
