大型铝合金焊接件焊后去应力时效的工艺研究

Technology research on distressing aging of welded structures of large aluminum alloy after welding

通过人工时效处理的方法可以使焊接结构件中的材料ZL101A由T4状态达到T5状态，并且可以减少大型铝合金焊接结构件焊接变形，降低焊接后的残余应力．

Materials ZL101A can from T4 to T5 state in welded structure by artificial aging treatment method, moreover,this method can reduce welding distortion of welded structures of large aluminum alloy, and lower residual stress after welding.
