Embodiment 1
[0047] Such as figure 1 As shown, a metal material high-energy beam addition and subtraction-on-line laser ultrasonic detection composite processing method, the specific operation includes the following steps:
[0048] The high-energy beam spray head 1 forms a deposited workpiece 3 with a certain number of layers according to the preset planned layered cross-section high-energy beam scanning path;
[0049] According to the specific process parameter settings, the material reduction tool 4 performs necessary material reduction processing on the deposited workpiece 3, removes the step effect and processes the surface detection plane;
[0050] Planar scanning of the newly deposited material after material reduction is carried out by the laser ultrasonic probe 5, and the laser ultrasonic signal is used to determine whether there is a subsurface defect 2 on the surface or inside of the material and determine its position;
[0051] If an intolerable subsurface defect 2 is detected,...
