小径管对接焊缝超声自聚焦相控阵检测装置
摘要：
本实用新型涉及小径管对接焊缝超声自聚焦相控阵检测装置，包括超声相控阵仪器、60°横波楔块、7.5MHz自聚焦超声相控阵探头、链条扫查架和微型编码器。所述链条扫查架可相对小径管活动地安装于小径管上，所述60°横波楔块和7.5MHz自聚焦超声相控阵探头相互连接并固定于所述链条扫查架，所述7.5MHz自聚焦超声相控阵探头发射的超声波经所述60°横波楔块进入小径管进行扫查，扫查结果反馈至超声相控阵仪器作进一步处理。所述微型编码器固定于所述链条扫查架，记录7.5MHz自聚焦超声相控阵探头于小径管轴向运动轨迹。本实用新型实现转动检测装置一周就可以确认待测管对接焊缝缺陷的大小和位置，提高检测的效率。
摘要（英）：

The utility model relates to a path pipe butt weld supersound self -focusing phased array detection device, sweep including ultrasonic phased array instrument, 60 shear wave voussoirs, 7.5MHz self -focusing ultrasonic phased array probe, chain and look into frame and miniature encoder. The chain sweep look into the frame relatively the path pipe install on the path is managed movablely, 60 shear wave voussoir and 7.5MHz self -focusing ultrasonic phased array probe interconnect are fixed in the chain is swept and is looked into the frame, 7.5MHz the ultrasonic wave warp of self -focusing ultrasonic phased array probe transmission 60 the shear wave voussoir gets into the path pipe and sweeps and look into, sweeps to look into result feedback and further handle to the ultrasonic phased array instrument. Miniature encoder is fixed in the chain is swept and is looked into the frame, and record 7.5MHz self -focusing ultrasonic phased array pops one's head in in path pipe axial motion orbit. The utility model discloses realize rotating detection device a week and just can confirm the efficiency of await measuring tub size of butt weld defect and a position, improvement detection.
