目前金属胶接的主要形式是结构胶接。由于这种胶接结构具有很多优点,所以用途及为广泛,并更多地在飞机上用作承力构件。但是,由于在材料、工艺上的各种因素的局限性,产生各种类型的胶接缺陷。因此,对材料、工艺质量的控制及无损检测方法的研究已引起人们的极大重视。在产品试制,生产的不同阶段,质量控制的主要内容是不同的,见下图。目前我厂胶接结构处于批生产阶段。批 At present, the main form of metal adhesive is structural adhesive. Because of the many advantages of this bonded structure, the use is widespread and is more used as a bearing member on aircraft. However, due to the limitations of various factors in material and process, various types of bonding defects occur. Therefore, the control of materials, process quality and nondestructive testing methods have drawn great attention. In the product trial, production of different stages, the main content of quality control is different, see below. At present, our factory cementing structure is in batch production stage. Batch
