摘要
Abstract
In this study,the effects of the pin tool and processing parameters of friction stir welding of 7050 aluminum alloy joint were examined.The results indicate that an improper design of the pin tool and/or an unsuitable parameter can cause an unsound weld.The improper dimension of the pin tool shoulder is the main factor resulting in the void defect. Too much heat input may result in the flash and tunnel defects. Under the present conditions,a good welding formation can be obtained by employing the tool Ⅲ with a rotating speed of 300 rpm and a moving speed of 95 mm/min.关键词
