Aluminum　alloys　have　been　proved　to　be　the　most　acceptable　material　for　weight　reduction　for　automobile　bodies.　Therefore　the　process　to　join　aluminum　alloys　to　the　traditional　material　such　as　low　carbon　steel　has　to　be　developed　in　vehicle　body　assembly.　The　methods　to　join　aluminum　alloy　to　steel　material,　including　arc　welding/brazing,　laser　welding,　resistance　spot　welding,　and　friction　stir　welding,　were　collected　and　discussed　in　the　paper.　To　help　the　designer　to　estimate　the　joint　strength　of　various　methods,　the　joint　strengths　and　failure　modes　of　steel/Al　dissimilar　materials　joint　under　static　tensile　loading　were　focused　on.　Moreover,　the　trend　of　the　joining　method　for　dissimilar　materials　is　also　discussed.
