Multi-Parameter Taguchi Robust Design for Performance Study ofSteel-Aluminum Spot Welding Joints
Bao Li，Wang Di （Pan Asia Technical Automotive Center，Shanghai 201216）
Abstract：This paper primarily introduces research on the process optimization of steel-aluminum spot welding jointperformanceand therobust designof welding parameters.Using the Pugh Matrix Analysis，the study compares solutionssuchasenhancedrivet materials，modifiedrivet structures，andoptimizedriveting/spotwelding parameters basedonfactorsincluding joint strength，weldnuggetdiameter，andcostefficiency，ultimatelyselectingsteelaluminum spot welding as theoptimal strategy.Subsequently，the Taguchi Methodand orthogonal experimentsare employed tostudythe influenceof weldingcurrnt，welding pressure，welding time，and electrodecapdiameteron joint strength of steel-aluminum spotwelding.Finall，asetofoptimalwelding parametersare selected from theperspective of maximizing shear strength，and steel aluminum spot welding and shear testsare conducted to verify their effectiveness and robustness.
Keywords：Stel-aluminumresistance spot welding，Pugh matrix，Taguchi method，Weldingparamters， Robustness
1前言
研究表明，整車質(zhì)量每減輕 10% ，傳統(tǒng)燃油車能耗可減少 5%～8% ，純電動車型續(xù)駛里程可提升12～13km ，而我國2025年新能源汽車滲透率預(yù)計(jì)突破 50% ，輕量化技術(shù)對突破續(xù)航瓶頸具有關(guān)鍵價值。（剩余3870字）
