Abstract
A friction stir welding system can reduce the likelihood of oxide formation in the work pieces being friction stir welded by forming an inert gas atmosphere in which the friction stir welding process is performed. The friction stir welding system includes one or more inert purge gas sources that direct inert purge gas towards the forming friction stir weld. The inert purge gas can be directed towards the forming weld from both an upper and a lower side, which further reduces the likelihood of oxide formation. Additionally, the friction stir welding system can include one or more housings that contains the inert purge gas about the forming friction stir weld, such as about an upper and lower side of the friction stir weld.
