本SAE信息报告的范围是提供无损检测领域应用的超声波基本信息。第2节列出了详细信息的参考。超声波检测是一种通用的无损检测方法，适用于大多数固体材料，金属或非金属。检查的材料包括钢、铝、铸铁、混凝土、橡胶、玻璃和塑料。通过这些测试，可以检测到表面和内部不连续性，如搭接、接缝、空隙、裂纹、气孔、夹杂物、粘结不良和气孔。材料厚度可以从一侧精确测量。在某些条件下，可以检查高温下的材料。

The scope of this SAE Information Report is to provide basic information on ultrasonics, as applied in the field of nondestructive inspection. References to detailed information are listed in Section 2. Ultrasonic testing is a versatile nondestructive inspection method which is applicable to most solid materials, metallic or nonmetallic. Materials inspected include steel, aluminum, cast iron, concrete, rubber, glass, and plastics. Through these tests, surface and internal discontinuities such as laps, seams, voids, cracks, blow holes, inclusions, lack of bond, and porosity can be detected. Material thickness can be accurately measured from one side. Under certain conditions, materials at elevated temperatures can be inspected.
