The paper introduces the process optimization method of TA2 components, such as increasing finishing proess, strengthening the liquid control, improving welding argon gas protection, to minimize the chance of TA2 fine powder adhering to the wall. The experiment reaches the expected effect and reduces the cost. It mainly introduces the TA2 cleaning technology of the tee through, right through with large length to diameter ratio of the high cleanliness requirements pressuring piping, provids a new method for tailings sensitive parts cleaning, and the result is highly transformed with innovation. The paper developes the TA2 detecting method of the tee through, right through of the high cleanliness requirements pressuring piping, provides the fine powder of quantitative tools, and the military, social benefits. This method has been tested by different products with stable and reliable performance.
