Problems solved by technology

The couplant used in these devices is often not easy to remove, resulting in additional couplant cleanup after inspection
In contact ultrasonic flaw detection, the force is often uneven when the probe touches the object to be inspected
In addition, there is currently no systematic and efficient ultrasonic testing method for aluminum alloy ingots to achieve the purpose of quality control

Abstract

The invention relates to an ultrasonic testing device for an aluminium alloy slab ingot. The ultrasonic testing device comprises an ultrasonic equipment support (6), a portable ultrasonic apparatus (7), a probe line (8), a water switch (11) and a pedestal (16). The ultrasonic testing device is characterized in that the pedestal comprises three support balls. The probes can divided into two types of a water-spraying type straight probe and a contact type straight probe according to functions of the probes. The ultrasonic testing device also comprises a connecting rod (9) and a steering shaft (15). With the ultrasonic testing device, conditions that a detection personnel bends down in a detecting process can be prevented through the effects of the connecting rod (9) and the steering shaft (15); fatigue of the detection personnel can be alleviated; and the ultrasonic testing device is adaptable to detection work of workpieces in different specifications. The invention also provides a method for using the ultrasonic testing device.

Description

technical field [0001] The invention relates to an ultrasonic detection device, which is applied to a flaw detection device for aluminum alloy materials, and also relates to a method for using the device. Background technique [0002] Considering the high quality requirements of aerospace aluminum alloy hot-rolled thick plates, the use of ultrasonic non-destructive testing technology to control the quality of ingots before hot rolling has become an important means to improve the yield of aluminum alloy hot-rolled thick plates. [0003] Internal defects that affect the quality of ingots include shrinkage cavities, porosity, pores, and non-metallic inclusions. Internal defects are generally detected using ultrasound or radiation. The surface defects that affect the quality of ingots are mainly edge surface cracks. Surface cracks in ingots are likely to propagate further during press working. The internal defects of the slab can be effectively found by using ultrasonic longi...
