On November 1, 2013, the non-destructive testing group of the China Shipbuilding Engineering Society organized by the Changchao Electronics Research Institute was successfully held in Changzhou Parkson Hotel in 2013. With the rapid development of marine engineering manufacturing projects and higher manufacturing requirements, marine engineering A large number of high-strength, corrosion-resistant materials with high requirements are used in engineering projects, and higher requirements for non-destructive testing technology are also put forward. During the meeting, the representatives conducted in-depth discussions on the application of phased array technology to detect small pipe girth welds, the prospect of the shipbuilding industry, the qualification of non-destructive testing personnel, the research and application of special colored flaw detection agents, and dry magnetic powder. All representatives of the conference visited Changchao Electronics Research Institute and gave unanimous praise to the company's development and prospects in the non-destructive testing industry.
