日本焊接给人总的印象是:工艺技术先进,自动化程度和生产效率高,焊接质量控制严格。但是,我们在日本参观学习期间,所看到的铆焊厂的装备,并非都是那么新型或高度自动化,有的工厂甚至不如我国许多化机及锅炉生产专业工厂,然而生产效率却相当高。这就更应引起我们的关注,更有学习和借鉴的实际意义了。一、各种焊接方法的应用情况在日本,在化工设备、压力容器及锅炉制造工厂,手工电弧焊的应用范围愈来愈小,几乎只有在自动焊尚有困难的部位,
Japanese welding gives the general impression is: advanced process technology, automation and production efficiency, strict control of welding quality. However, during our visit to Japan, we did not see all the new or highly automated equipment manufacturing of the welding plant. Some factories did not even have as many factories and specialized boiler manufacturing factories in China, but the production efficiency was rather high. This should even arouse our concern, more practical significance of learning and reference. First, the application of a variety of welding methods In Japan, in the chemical equipment, pressure vessels and boiler manufacturing plant, manual arc welding less and less scope of application, almost only in the automatic welding is still difficult parts,
