Abstract
The X-ray diffraction method (iXRD) has been applied into the measurement of residual stress ultrasonic impact ultrasound before and after the impact test process residual stress of aluminum alloy welded joints. Research different inrush current, different impact time of different ultrasonic impact of the process on the residual stress of welded joints of aluminum alloy welded joints welding residual stress distribution and its variation. We can study the distributing status and disciplinarian, and testify the step to adjust the welding residual stress by ultrasonic impact treatment. The research supplys the data supports for welding residual stress engineering disposal and weld joint assistant consolidation to improve abilities against the gatigue. The research shows appropriate welding and ultrasonic impact treatment technics can effectively adjust welding residual stress and meet the RAMS demands about the product.
