Scope

This Standard specifies the principle, equipment, workflow, treatment effect
comparison and control report for using a sound beam with a certain energy
and directionality (elastic beam in a solid) to control the residual stress on the
surface and inside of metal materials.
This Standard is applicable to the on-site in-situ reduction and homogenization
of the assembly and welding of large metal components such as metal
containers, steel structures, pipelines, tracks, car bodies, aerospace cabins.
The control of the surface and internal residual stress of other non-metallic
sound-transmitting materials can also use it as reference.
