  • System and method for manufacturing tubular products from tubular workpieces
    Patent number: 6029487
    Abstract: A system for forming tubular metal products from tubular workpieces by hydroforming achieving single-step radial expansion of 70-150% with high dimensional accuracy. Enhanced single-step radial expansion is achieved by maintaining a predetermined functional relationship among the driving parameters of the hydroforming process and by increasing the plasticity of the workpiece by employing the fractional deformation effect and by applying ultrasound oscillations and alternating angular strains to the workpiece.
