摘要 针对常规超声检测方法在进行三维多变断面转轮焊缝检测时存在的局限性,介绍了相控阵超声检测技术的特点。根据转轮焊缝容易出现的缺陷类型制作了模拟试块,设计超声相控阵检测工艺并进行检测,对检出缺陷进行常规超声检测验证。结果表明,超声相控阵技术可明显提高检测效率及检出能力,但对位向不好的层间未熔合,仍需配合直探头在焊缝弧面进行补充检测。 Aiming at existing boundedness of conventional ultrasonic testing method in testing 3D changeable cross-section runner weld,this paper introduces features of phased array ultrasonic testing technology.According to defect types easy to appear of runner weld,it makes simulation samples and designs ultrasonic phased array testing technology to test detected defects and proceed conventional ultrasonic testing verification.The result indicates that ultrasonic phased array technology is obviously able to improve testing effectiveness and detecting ability but it is not able to finish fuse of interlamination of bad exposure.Thus,it is necessary to carry out supplementary testing on the weld cambered surface by coordinating with normal probe.
