Abstract
The advantages of oxide removal prior to resistance spot welding mill-finish aluminum sheet are well documented. The process of localized oxide removal through the sputtering action of a plasma arc has been integrated into a spot welding cycle at rates compatible with most automotive processes. The resulting process provides a low electrode-sheet interface resistance, having profound effects on electrode life and weld quality consistency.
