Abstract

The invention relates to a method and a device for calibrating probe in ultrasonic detection equipment. The method is used in ultrasonic detection equipment for welding quality of electric contact, a calibration sample is fixed in a water tank for measuring, water absorption sponge is arranged on a path of a probe to a calibration sample, when each workpiece starts to be detected, the probe backs on the calibration sample, in order to calibrate precision and clean the probe, and consistency calibration to the ultrasonic probe and probe cleaning are implemented. By introducing the calibration sample, laboratory ultrasonic detection precision can be extended onto an on-site measuring device, and measuring result of the measuring device can be traced back. The method and the device enable the detection of the electric contact welding quality to obtain a consistent detection result with different equipment, at different time and under different work environment, can clean the ultrasonic probe while calibrating the equipment.

Description

technical field [0001] The invention relates to a method in the field of ultrasonic detection of electric contact welding quality, in particular to a probe calibration method and device in ultrasonic detection equipment. Background technique [0002] Ultrasonic testing is a common method in non-destructive testing, and it is also a common testing method for weld quality. Most of the ultrasonic testing is to judge the internal gap and material distribution of the workpiece by detecting the transmission intensity or reflection intensity of the ultrasonic wave through the workpiece to be tested. Generally, qualitative detection only needs to be able to obtain the difference in the ultrasonic reflection intensity inside the workpiece. The distribution characteristics inside the workpiece can be characterized. [0003] In the welding quality inspection process of electrical contact points, the welding quality of the weld is detected and judged by detecting the reflection intensi...
