On November 05-06, 2020, the second China Wind Turbine Blade Operation and Maintenance Technology Symposium was grandly opened in Yancheng, Jiangsu, on the beautiful coast of the Yellow Sea. More than 300 representatives from all over the country participated in this seminar, covering the entire upstream and downstream industry chain of enterprises in the wind power industry, including owners, complete machines, blades, operation and maintenance, testing and certification, and scientific research. More than 20 technologically rich themed reports and a high-level dialogue among experts have presented a rare technological feast for the wind power operation and maintenance industry. Lv Guiyang, General Manager of Ge Yu Technology, and relevant technical personnel were invited to participate, and industry leaders and experts gathered together to discuss the future of wind power.             在会议“安全运维、完美修护、提技增功”的主题引导下，大家对风电叶片的运维服务都提出了自己的意见建议，为风电运维的技术发展贡献了一份力量。           戈昱科技重磅推出的GSCAN-200便携式超声相控阵螺栓检测仪、CTS-PA322T相控阵全聚焦3D螺栓检测仪及USGNet在线超声应力测量模块齐“亮相”于论坛，戈昱科技技术人员为前来观摩的领导、专家及其他嘉宾详细介绍设备在风电行业的无损检测应用、及其新设备的功能特点等。讲解得到了广大参会嘉宾的关注和认可，同时还达成了不少新的合作意向。          

At the invitation of an A-level testing company in Anhui Province, a team of three DR testing engineers from Ge Yu Technology Engineering Department came to the designated testing project site of the Provincial Special Inspection Institute on July 7th to evaluate the project site and select 20 randomly inspected welded joints; The on-site thermal conductivity pipeline is shown in the following figure:       The on-site inspection was carried out from July 8 to July 9. Since the heat transfer oil in the pipeline to be inspected could not be exported, our DR inspection engineer had conducted DR inspection on the site in Hefei Provincial Hospital, Anhui Province in the middle of June, The comparison result shows that the sensitivity of the DR imaging plate can meet the acceptance requirement of AB level qualification, while the traditional radiographic film cannot see the 13th wire diameter (effective continuous length 1cm), which cannot meet the standard requirements; Therefore, the DR method -1210 imaging board combined with a 200KV high-frequency machine was selected for this detection; The detection effect is shown in the following figure:             On site filming process：
