    • Abstract
  • Proper extrusion force is critical to ensure weld strength of the spiral weld tube during hi-frequency butt-welding process. Based on the resistance of the blank against elastic- plastic deformation calculated with the energy method and related welding pressure calculated with the direct method,the formula for computing the extrusion force was derived. Relevant experiments show that the said theoretical analysis is correct.
