Technical Field

[0001] The utility model relates to the technical field of cold welding detection, in particular to ultrasonic cold welding detection equipment. Background Art

[0002] Ultrasonic cold weld detection is a non-destructive detection technology that is often used to detect cold weld defects in welded joints. In this technology, ultrasound is used to penetrate the weld joint, and then the detector receives and analyzes the reflected ultrasonic signal. When ultrasound encounters defects inside the weld joint, such as pores, inclusions, cracks, etc., it will cause part of the ultrasound to be scattered or reflected, thereby producing a signal pattern different from the normal area. When welding cylindrical pressure pipes, it is usually necessary to inspect the weld to ensure the welding quality and the safety of the pipeline. In the past, this inspection was usually performed manually, and the workpiece needed to be moved or rotated manually during the inspection process to inspect the workpiece, which was time-consuming and laborious. At this time, ultrasonic cold weld detection equipment is needed to replace manual inspection, and the existing ultrasonic cold weld detection equipment still has some shortcomings, such as the inability to replace manual movement and rotation of the workpiece more conveniently, and the inability to perform weld inspection on pressure pipes of different sizes.
