[0002] Excavator is one of the most widely used construction machinery. The excavator working device is the main operating component, of which the boom is located at the rear of the working device and has a large load. The excavator boom is a complex box-type component, which is subjected to alternating loads such as tension, compression, shear, torsion and bending during use. Therefore, it is very important to ensure that the strength, rigidity and stability of the boom meet the use requirements.

[0003] The existing ultrasonic phased array weld detection structure for excavator booms has certain disadvantages when used. The existing detection structure requires manual holding of the ultrasonic phased array detector for a long time when in use, and requires repeated holding of the ultrasonic phased array detector around the weld for detection, which makes the workers' workload heavy. Long-term detection is prone to fatigue, resulting in a decrease in the accuracy of the detection results, thereby reducing the welding quality of the excavator boom.

[0004] Therefore, in order to solve such problems, we proposed an ultrasonic phased array weld detection structure for excavator boom. Utility Model Content
