Due to the melting point differential and solubility issues, conventional resistance spot welding is not feasible for many multi-material applications. Resistance spot welding is not feasible for multimaterial applications owing to the difference in melting points and solubility issue. Riveting and more specifically self pierce riveting utilizes coated boron steel self-piercing rivets. They have: ? Corrosion issues due to difference in galvanic potentials especially between steel and magnesium ? Issues with end of life recycling challenge ? the application or SPR's introduce significant change in the body shop operations which add additional cost and lost production when existing operations are utilized Solution/Invention: Using the high velocity riveting system we effectively eliminated the use of rivet to form a metallurgical bond avoiding galvanic corrosion, cost and life cycle issues, with minimal impact to existing body shop operations. Other benefits: Description: Utilizes a handheld system, so it could be used for any robot using resistance spot welding (low capital investment to implement and doesn't require significant changes to manufacturing line) Not using steel so less issues w/ corrosion Do not need to drill holes (reduces manual labor. steps) Recyclable(without steel rivets you have a 100% BIW recyclable)
