二、几种典型零部件的质量控制与检测随着大型铸件、锻件及焊接结构件向着高性能、大型化发展,其生产工艺复杂,而且对其质量要求极为严格。因此,必须采取多种测试技术检查评定钢材各项性能和内部质量。下面以几种典型零部件为例,说明其生产过程中各工序间进行质量检查的内容、采用的测试技术和装备。 Second, the quality control and testing of several typical components With the large castings, forgings and welded structural parts towards high-performance, large-scale development, the production process is complex, and its quality requirements are extremely strict. Therefore, we must take a variety of test techniques to assess the steel performance evaluation and internal quality. Here are some typical components, for example, explain the production process of quality inspection between the contents of the test techniques and equipment used.
