Problems solved by technology

[0004] Existing aluminum battery boxes are generally welded by several aluminum alloy plates. The quality of the welds determines the quality of the aluminum battery box. In order to ensure the overall quality of the aluminum battery box, it is necessary to inspect the welds, which were manually passed before. Hand-held ultrasonic probes are used for weld inspection. This inspection method is time-consuming and laborious, which is not conducive to the rapid production of enterprises.

Description

technical field [0001] The invention relates to the technical field of electric vehicles, in particular to an internal defect detection device for welding seams of aluminum battery boxes. Background technique [0002] At present, countries all over the world are vigorously developing new energy vehicles. The development of energy saving and new energy vehicles is one of the important measures to reduce oil consumption and reduce carbon dioxide emissions. [0003] In a good development environment, the technology of pure electric vehicles is changing with each passing day, and the technology growth of battery boxes is also constantly changing. The aluminum alloy battery box is light in weight, can reduce the weight of the whole vehicle, and has a certain effect on the cruising range. [0004] Existing aluminum battery boxes are generally welded by several aluminum alloy plates. The quality of the welds determines the quality of the aluminum battery box. In order to ensure t...
