Problems solved by technology

However, these methods are limited to the online signal acquisition of a single detection object, and cannot comprehensively detect and reflect the quality information of the formed component. Moreover, these methods are only applicable to a specific metal additive manufacturing equipment, and do not have scalability, versatility, and universality.
[0006] Therefore, the existing detection technology cannot meet the quality control requirements of key and important components of feed-type metal additive manufacturing in important fields such as aerospace, and develop a system and method suitable for online non-destructive testing of the quality of feed-type metal additive manufacturing components , become more urgent and important

Abstract

The invention discloses an online nondestructive detection system and method of quality of manufacturing members of metal additional materials and belongs to the field of online nondestructive detection. The system comprises a moving detection vehicle, a guidance rail, an online signal detection module and a control system. A column is arranged on the vehicle body of the moving detection vehicle. The guidance rail is movably connected to the column. The online signal detection module is movably connected to the guidance rail. Multiple probes are integrated into the online signal detection module and comprise probes used for detecting compositions, defects, deformation, stress, size precision and surface coarseness. During detection, the probes can be embedded into a 3D printing head of a feeding type additional material manufacturing device or be fixed on the moving detection vehicle. The probes are in signal connection with the control system. The invention also provides a method for carrying out online nondestructive detection of the system. According to the invention, the system and the method are widely applicable, highly expandable and capable of achieving onsite or remote online detection of manufacturing processes of feeding type metal additional materials.

Description

technical field [0001] The invention relates to a system and method suitable for online non-destructive testing of component quality in feeding-type metal additive manufacturing, specifically related to online non-destructive testing of component components, defects, deformation, stress, dimensional accuracy and surface roughness, etc., belonging to online non-destructive testing field. Background technique [0002] Additive manufacturing technology (Additive manufacturing), also known as 3D printing technology, is a high-end digital manufacturing technology based on the principle of layered manufacturing and layer-by-layer superposition forming, which is processed by "additive" processing from three-dimensional CAD data of parts.
