1. the treatment process of bullet train aluminum alloy welding connecting structure, it is characterized in that it comprises the steps:

  • one, belongs to weld seam, toe of weld, heat affected zone, four kinds of situations selection ultrasonic impact pressure heads of the full welded seam area of mother metal for the weld, the cross section of described ultrasonic impact pressure head is " bar shaped " or " circle ";

    Being " bar shaped " ultrasonic impact pressure head for weld seam and toe of weld selection cross section, is " circle " ultrasonic impact pressure head for heat affected zone and the full welded seam area selection of mother metal cross section;

    Two, the ultrasonic impact pressure head of choosing is assembled on ultrasonic impact equipment;

    Three, opening ultrasonic impact equipment the shock treatment of position is one by one carried out on the surface of aluminum alloy welding connecting structure, evenly arranges and is adjacent in each position of shock treatment, forms the nanometer layer of 10 μ

    m on the surface of aluminum alloy welding connecting structure.
