在批林批孔运动的推动下,全国各条战线革命和生产形势一派大好,随着社会主义革命和社会主义建设的飞速发展,燃化、轻工等工业部门对阀门产品提出了更高、更新的要求,而等离子喷焊工艺在阀门上的应用,就是解决阀门产品质量问题的有效措施之一。为此,一机部重型通用局委托通用机械研究所和上海重型机械制造公司,于1974年6月25日至30日在上海阀门厂召开“高、中压阀门等离子喷焊现场经验交流会”,来自全国22个省、市、自治区的工厂、学校、科研机关等近60个单位,计127名工人、干
Driven by the pro-xi-bian movement, the revolution and production situation in all fronts in various fronts in our country have been fantastic. Along with the rapid development of the socialist revolution and socialist construction, the industrial sectors such as fuel oil and light industry put forward higher and higher demands on valve products, Updated requirements, and plasma spray welding process in the valve on the application, is to solve the valve product quality problems one of the effective measures. To this end, a machine Heavy General Bureau commissioned by the General Machinery Research Institute and Shanghai Heavy Machinery Manufacturing Company, in June 25, 1974 to 30 in Shanghai Valve Factory held a “high-pressure valve on-site plasma spray welding experience exchange meeting” , Nearly 60 units from factories, schools and research institutes in 22 provinces, cities and autonomous regions nationwide, counting 127 workers,
