Bureau of Chemical Industry two Bureau X flaw learning classes in October 30, 1980 to November 16 held in Jiujiang. Lasted 18 days. Forty flaw detection technicians and workers from 24 units in Beijing, Shanghai, Guangzhou, Shenyang, Xining, Chongqing and Xi’an attended the seminar. The purpose of holding this workshop is to train non-destructive testing talents for the units affiliated to the Second Bureau of the Ministry of Chemical Industry to meet the needs of the “four modernizations.” The classes gave a detailed explanation on the physical basis of X-ray and magnetic particle inspection, basic flaw detection method, flaw detector performance, flaw detection technology and related technical standards of typical pressure vessels and parts.
