我和同事、同行们,带着极大的兴趣和期望赴德,参加了四年一届的国际埃森焊割会,这是我第六次参加这一盛会,与往次有所不同的是,我是以双重身份与会的。过去,我都是以华南理工大学学者的身份参加学术交流和观展的,而这次还兼以广州同诚设备技术公司董事长、工作人员的身份出席会 My colleagues and colleagues, with great interest and expectation, went to Germany to attend the four-year International Essen Hourging Conference, which is the sixth time that I attended this event and was different from the past. Yes, I attended in a double capacity. In the past, I attended the academic exchange and exhibition as a scholar of South China University of Technology, and this time I also attended the meeting as the chairman and staff of Guangzhou Tongcheng Equipment Technology Co., Ltd.
