课程名称：NDT - 渗透测试等级2 课程概述：本课程涵盖了渗透测试（也称为液体或染料渗透测试）的概念，这是一种用于检测非多孔金属材料表面裂缝和空洞的无损检测方法。液体渗透测试是最简单和最受欢迎的无损检测方法之一。在本课程中，我们将讲解完成PT认证所需的渗透测试培训相关概念。这对于确保符合NAS-410、SNT-TC-1A和NavSea技术出版物T9074-AS-GIB-010/271的要求至关重要。培训内容分为八个章节。 1. 渗透测试的历史、毛细作用与润湿、内聚力与附着力以及液体渗透测试的方法。 2. 表面准备、预清洗及各种液体渗透系统的介绍。 3. 安全注意事项、液氧材料、渗透剂应用技巧、渗透时间、温度限制、渗透剂过量去除技巧及过度清洗的注意事项、不同去除技巧的优缺点、显影剂种类及应用。 4. 结果的解读与评价，包括假性、非相关和相关指示。 5. 质量控制测试；Tam面板；比较块。 6. 术语及按产品形式如铸造、锻造等的产品缺陷；不同产品形态和焊接的方法讨论。 7. 按类型、方法、显影剂形式进行的系统分类；如润湿能力定义的渗透剂术语；程序要求。 8. 典型的资格和认证文件；SNT-TC-1A概述。 本课程内容符合ANSI/ASNT CP-105中列出的无损检测人员资格培训主题。该培训将满足液体渗透测试的多数认证文件要求，如SNT-TC-1A，并涵盖ANSI/ASNT CP 105大纲中列出的液体渗透认证主题。通过所有培训材料和考试后，学员将获得培训证书。
This course covers the concepts of Penetrant (also called Liquid or Dye Penetrant) Testing, an NDT method used to detect cracks and cavities open on the surface of nonporous metallic materials. Liquid Penetrant Testing is one of the simplest and most popular NDT methods for inspection.In this course, we will cover the required concepts around penetrant testing training necessary for completion of the PT certification program. This is essential for ensuring compliance as per NAS-410, SNT-TC-1A and NavSea Technical Publication T9074-AS-GIB-010/271.The training is divided into eight (8) chapters.Penetrant history, capillary action and wetting, cohesion and adhesion, and the methods of liquid penetrant testingSurface preparation; pre-cleaning; and the various liquid penetrant systemsSafety; LOX materials; penetrant application techniques; penetrant dwell times; temperature limits; excess penetrant removal techniques and over cleaning precautions; advantages and disadvantages of each removal technique; developer types and applicationInterpretation and evaluation; false, non-relevant and relevant indicationsQuality Control test; Tam panel; Comparator BlockTerminology; product discontinuities by product form such as casting, forgings etc.; discussion of methods to make the different product forms and weldingSystem classifications by Type, Method, Developer forms; penetrant terms such as wetting ability defined; procedure requirementsTypical qualification and certification documents; SNT-TC-1A overviewThis course content conforms to the training subjects listed in ANSI/ASNT CP-105, Standard Topical Outlines for Qualification of Nondestructive Testing Personnel. This training will meet most certification document for liquid penetrant testing such as SNT-TC-1A. It encompasses the subject matter listed in the ANSI/ASNT CP 105 outline for liquid penetrant certification. Upon satisfactory completion of all training material and exams, a training certificate will be issued.
