【国家标准】 金属材料　残余应力　声束控制法

This standard specifies the principle, equipment, procedure, comparison of processing effects and control report for the surface and internal residual stress control for metallic materials by using sound beams (elastic beams in solids) with certain energy and direction.
This standard is applicable to on-site or in-situ reduction and homogenization of assembling and welding residual stress of large metal components such as metal containers, steel structures, pipes, rails, vehicle bodies, and aerospace cabins.The control of surface and internal residual stress of other non-metallic sound-transmitting material components may also refer to this standard.
