常言道“一分耕耘,一分收获”。我刊自第8期刊登了“技术交流百家争鸣”栏目以来,受到了广大热心读者的广泛关注,他们积极撰稿讨论技术问题,为促进我国焊接事业的发展而努力。现现选登部分热心读者文章,同时也希望更多的读者参与有关技术讨论,共同促进焊接事业的进步。 As the saying goes “a hard job, a gain.” Since the publication of the section titled “The Contest for Technology Exchange in a Hundred Schools of Thought” since the 8th issue, I received wide attention from the enthusiastic readers. They actively wrote and discussed technical problems and worked hard to promote the development of China’s welding industry. Selected enthusiastic readers are now selected articles, but also hope that more readers to participate in the technical discussions to jointly promote the progress of welding.
