Description
An experimental study was carried out to characterise the types of defect which may occur in friction stir welding (FSW) when operating outside the standard processing window and to determine the causes of these defects. Friction stir welds were made using 2014A aluminium alloy plates of thickness 6 mm, varying process parameters such as welding speed, welding force, tool pin height and joint fit up to generate defects. X-ray and ultrasonic testing and metallographic examination were used to inspect the welds for defects. The types of defect found (voids, joint line remnants, root flaws) and their causes are discussed.
