Friction stir welding of aluminium alloys has been cited by many users as a cost-saving process. This is in part due to the elimination of consumable costs, but is also due to the ability to make most welds in one or two passes, even in thick material. FSW is also an efficient process in terms of energy consumption, which can also lead to significant cost savings. The fully automated nature of the process also reduces labor costs and the possibility of defects. Visit our friction stir welding page to learn more.
