为了向同志们提供国外近年来焊接技术方面的情况和动向,我们从国外刊物中搜集了一些资料,经整理写成本文,供读者参考。由于我们对马、列的书和毛主席著作学得不够,路线斗争觉悟、业务能力不高,文中错误之处,欢迎同志们批评指正。 In order to provide comrades with information about the welding technology in foreign countries in recent years, we collected some information from foreign publications and compiled them into texts for readers’ reference. Because we have not learned enough from the books of Marxism-Leninism, Mao Zedong and Chairman Mao, the awareness of the route struggle, the lack of professional ability, and the mistakes in the text, we welcome comrades to criticize and correct them.
