背景技术Background technique
随着环保要求的越来越高，汽车尾气排放法规的日益严格，尾气后处理技术是必须采用的技术措施。而SCR能够满足国IV、V及国Ⅵ排放标准。SCR的封装工艺简化，降低成本也越来越重要。通用工艺首先是内组件焊接完成，然后内组件与筒体装点，再总成焊接进出气管组件。但是该工艺焊接进出气管组件是三层叠加，对内组件焊接工序、零部件尺寸要求比较高，极其容易造成焊缝虚焊、漏焊，导致SCR封装出现漏尿素现象。As environmental protection requirements become higher and higher, and automobile exhaust emission regulations become increasingly strict, exhaust gas after-treatment technology is a technical measure that must be adopted. The SCR can meet the national IV, V and national VI emission standards. It is more and more important to simplify the packaging process of SCR and reduce the cost. The general process is first to complete the welding of the inner components, then decorate the inner components and the cylinder, and then assemble and weld the inlet and outlet air pipe components. However, the process of welding the inlet and outlet air pipe components is a three-layer superimposition, and the requirements for the welding process of the internal components and the size of the parts are relatively high, which is extremely easy to cause false welding and missing welding of the welds, resulting in urea leakage in the SCR package.
