Abstract
With the increasing industrial automation, the requirement of the non-destructive testing technology tends to be more and more urgent. In the paper, regarding the difficulty of testing the surface integrity, the author firstly introduces the principle of the non-destructive testing technology, and then emphatically analyzes the application in the field of metal surface, finally presents the advantages and disadvantage of the non-destructive testing technology. This paper gives the basic structure and working mechanism of the laser ultrasound non-destructive testing system. The experiment proves the feasibility and effectiveness of the system. At last, the problem and development orientation of the laser ultrasound non-destructive testing technology are also pointed out.
