建成机械厂在制造1250瓩水輪發电机机组中,采取了‘以小拼大”的方法,将每塊600公斤共八塊組成的重达5吨的多变断面座环用板極电渣焊焊接成功。工厂没有“洋”电渣焊設备及专用工具,我們就組成四結合研究组(領导,技术人員,学生,工人)一起研究,用“士洋結合”的办法进行創造性的試驗,前后共试验十多次,掌握了电源、电压、电流、操作方法、保温、造型等初步經驗性的規律,开辟了沒有“洋”設备以士办法进行电渣焊的道路,为沒有大設备也能生产 Built machinery factory In the manufacture of 1250 瓩 hydro-generator unit, taken a “small spell” approach, each of a total of eight 600 kg composed of a variety of 5 tons of variable section seat ring plate electrode slag Welding success. The factory does not have “foreign” ESR equipment and special tools, we formed a group of four with the research team (leaders, technicians, students, workers) together to study, with the “foreign Yang combination” approach to creative Test, a total of more than 10 times before and after the test, mastered the power, voltage, current, operation method, insulation, modeling and other preliminary empirical rules, opened up without the “foreign” equipment to do the method of electroslag welding roads, Large equipment can produce
