It is not 2 dissimilar metals. You cannot weld aluminum to steel. There is a steel tab molded inside the end of each aluminum 5 spoke or I should say the aluminum is poured-molded around the steel tab leaving a portion of the steel tab sticking out at each end of the spoke-that portionof the steel tab is welded to the rim.
