Since its inception in 1985, China Welding Expo has experienced nearly 20 years of development from the development to the growth of the welding industry, from the planned economy to the market economy. As the oldest event in China's welding industry, it has made positive contributions to the promotion of new welding technology in China and the technological progress of enterprises. This year's 19th China Welding Expo took the strategic opportunity of “Revitalizing the Northeast†by the Central Committee. For the first time, we joined hands with many excellent welding companies at home and abroad to perform in the northeast industrial city of Shenyang. In order to make the readers fully understand the situation of this exhibition, the journalist of the journal interviewed the head of the organizing committee, Yu Qingsheng, director of the Chengdu Electric Welding Machine Research Institute on the eve of the exhibition.
