Introduction
GB/T 45169—2025 Standard Overview
This standard specifies the principle, operators, sound beam control system, working process, inspection method and process record file of residual stress sound beam control method in the production process of additive manufacturing metal parts. It is applicable to arc additive manufacturing of aluminum alloy, titanium alloy and cemented carbide metal parts.
Background and significance of standard formulation
During the metal additive manufacturing process, complex thermal cycles lead to uneven residual stress inside the component, which seriously affects the performance and precision. The sound beam control method injects ultrasonic waves into the material to reduce and equalize the residual stress, significantly improving the quality of the product.
Explanation of core terms
Sound beam control
The process of injecting sound waves or elastic waves with a certain energy into the material to reduce and equalize the residual stress.
Exciter
A device that generates controllable ultrasonic energy, usually made using the piezoelectric ceramic principle.
